Chemical Name: Disuccinoyl Peroxide
Concentration: Between 72% and 100% content
Physical Appearance: Usually appears as a white to off-white crystalline solid
Odor: Mild, sweet, sometimes barely noticeable
Recommended Use: Serves roles in polymerization processes, specialty syntheses, and occasionally in laboratory-scale oxidations
Hazard Class: Organic peroxide with strong oxidizing properties
Main Dangers: Readily ignites, may explode from heat, shock, or friction, releases irritating fumes on decomposition, sensitive to contamination
Health Hazards: Corrosive on contact, can burn skin and eyes, inhalation may cause respiratory irritation, ingestion leads to severe harm
Signal Words: Danger, Explosive, Oxidizer, Corrosive
Labelling: Strong precaution around combustibles and incompatible substances, wearing eye and skin protection, using non-sparking tools is essential
Disuccinoyl Peroxide: Active component, purity falls between 72% and 100%
Other Possible Ingredients: Some formulations carry minimal stabilizers or diluents, but pure batches avoid these; inert matter can influence hazards
Eye Contact: Immediately flush eyes with plenty of clean water for at least 15 minutes, pull back eyelids to ensure thorough rinse, medical help should not be delayed, damage can worsen fast
Skin Contact: Strip contaminated clothing, rinse skin right away with water and soap, watch out for delayed reactions such as blistering — some peroxides burn deeper than it first appears
Inhalation: Get to fresh air without delay, keep breathing normally, oxygen if trouble arises, emergency responders need suitable respiratory protection against fumes
Ingestion: Immediate medical care, rinse mouth but do not give anything by mouth to an unconscious person; no antidote, only supportive care
Onset of Symptoms: Always rapid, so acting without hesitation makes a difference
Extinguishing Media: Large volumes of water as a spray or fog work well; avoid dry chemicals or foam which can make organic peroxides more unstable
Unsuitable Agents: Dry powders, carbon dioxide, and alcohol-based extinguishers all risk violent reaction with this compound
Specific Hazards: Explosive decomposition at high temperatures, can produce thick, acrid smoke and toxic gases like carbon monoxide and organic acids
Personal Protection for Firefighters: Full protective equipment and self-contained breathing apparatus; consider remote strategy since close handling can invite explosions
Special Tactics: Move containers away if safe, keep surroundings well-cooled with spray, never use naked flames near spilled chemicals
Personal Protection: Evacuate the area, use non-sparking tools, maintain adequate ventilation
Spill Control: Douse with large quantities of water, sweep up very gently without friction, avoid metal shovels
Environmental Precautions: Prevent run-off into soil, drains, or any natural waterways since both acute and long-term ecological damage can occur
Cleaning Practices: Wear chemical resistant gloves, lab coat, and face protection, collect spilled material in a non-combustible, waterproof container
Decontamination: Rinse area thoroughly, ensure all residues diluted before disposal
Safe Handling: Keep away from heat, sparks, flames, and shock; never open containers roughly; static discharge can trigger dangerous results
Storage Requirements: Store at low temperatures (below 25°C ideally), in small quantities, within dedicated cool and ventilated cabinets, always separate from acids, bases, reducing agents, combustibles
Safe Practices: Post clear labels, only trained personnel allowed to handle, keep strict inventory, check containers regularly for leaks and swelling
Engineering Controls: Work with fume hoods or efficient local exhaust, explosion-proof apparatus for transfer and weighing
Personal Protection: Full eye protection (tight-fitting goggles), chemical-proof gloves (nitrile or neoprene), flame-resistant lab coats
Respiratory Protection: Suitable respirators for dust or vapors, especially if accidental decomposition releases fumes
Hygiene Measures: No food or drink allowed, thorough hand washing after handling, proper shower and eye wash stations in immediate reach
Appearance: Typically white crystalline powder
Molecular Weight: Specific gravity generally around 1.2-1.3
Odor: Faintly sweet
Solubility: Insignificant in water, soluble in many organic solvents, but high purity makes it unpredictable
Melting Point: Can differ depending on batch purity, but tends to decompose explosively near or above melting range
Vapor Pressure: Not significant under normal storage, but rises sharply under heat
Decomposition Temperature: Sensitive to heat, with violent breakdown at moderate warmth (above room temperature in some cases)
Auto-ignition: Prone to self-heating, especially when contaminated or stored improperly
Stability: Unstable at elevated temperatures or under light exposure; even pure material can decompose over time
Incompatible Substances: Strong acids, alkalis, reducing agents, heavy metals, and especially organic combustibles raise risk of runaway reactions
Hazardous Decomposition Products: Produces carbon monoxide, organic acids, possible toxic vapors under fire or slow heating
Reactivity: Vigorous decomposition with shock, friction, or static discharge
Acute Effects: Burns upon contact, eye and respiratory irritation, potential for permanent injury (such as corneal burns)
Chronic Effects: No well-documented evidence, but repeated exposure may increase sensitivity and cause severe dermatitis
Routes of Exposure: Skin, eyes, inhalation are primary, ingestion is rare but life-threatening
Other Data: No confirmed carcinogenic or mutagenic potential, though few high-quality studies exist due to the hazards in handling pure substance
Environmental Impact: High potential to contaminate soil and water due to persistence and reactivity; aquatic toxicity not fully studied but likely significant given related peroxides
Bioaccumulation: Not regarded as likely, but breakdown byproducts could pose indirect risk
Degradability: Unstable in the environment, yet incomplete coverts yield toxic intermediates which linger
Waste Treatment: Small quantities should undergo wetting with water and careful neutralization in controlled conditions, large batches must go to specialized hazardous waste facilities
Container Disposal: Rinse and destroy on-site under supervision, never reuse for food or casual purposes
Regulatory Caution: Strict ban on release to environment, some regions require additional documentation before shipment to treatment centers
Transport Category: Classified as dangerous goods for air, sea, and road transport
Packaging: Only allowed in explosion-proof, pressure-relief approved containers, with clear hazard symbols
Special Precautions: Prohibit carriage with combustibles or other oxidizers, require written emergency response plans during shipment, temperature control mandatory to reduce runaway risk
Workplace Regulation: High oversight under most regional and national chemical safety frameworks, limits on quantity stored and worked with, mandatory training for handlers
Reporting Requirements: Usage thresholds must be reported to environmental and safety authorities, clear documentation of inventory
Labeling Standards: Comprehensive safety pictograms and warnings, detailed procedure sheets accessible to all personnel, tracked in chemical safety audits
