Appearance: White to slightly yellow crystalline powder
Common Uses: Laboratory reagent, pharmaceutical synthesis, dye manufacturing
Odor: Faint aromatic odor
Hazard Classification: Toxic if swallowed, inhaled, or absorbed through the skin
Health Risks: Can cause severe irritation to skin, eyes, and respiratory tract, possible damage to blood and organs
Symbols and Pictograms: Skull and crossbones, exclamation mark
Long-Term Exposure: May result in anemia, organ damage, or increased cancer risk
Component: Phenylhydrazine sulfate
Concentration: High purity, typically over 99%
Impurities: Trace organic or inorganic byproducts, usually not contributing significantly to toxicity
Inhalation: Move to fresh air right away, get medical attention, support breathing as needed
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water for at least 15 minutes
Eye Contact: Rinse eyes gently but thoroughly under running water for at least 15 minutes, seek medical care
Ingestion: Do not induce vomiting, rinse mouth with water, seek immediate medical help
Suitable Extinguishing Media: Use water spray, dry chemical, or carbon dioxide
Hazardous Combustion Products: Produces toxic fumes including nitrogen oxides and sulfur oxides
Precautions: Firefighters should use self-contained breathing apparatus and protective gear due to release of hazardous fumes during combustion
Personal Protection: Wear protective gloves, chemical splash goggles, and lab coat; avoid dust generation
Containment: Scoop up solid material with minimal dust generation, transfer to a suitable container for disposal
Clean-up: Ventilate area thoroughly; clean residue with damp absorbent material to reduce risk of airborne particles
Handling: Ensure work area has proper ventilation; minimize exposure; avoid inhaling dust or allowing contact with skin
Storage: Keep the container tightly closed in a cool, dry, and well-ventilated area; store away from oxidizers and acids
Storage Containers: Use chemical-resistant containers with clear labeling to prevent accidental misuse
Engineering Controls: Work with this compound in a chemical fume hood, use local exhaust ventilation
Personal Protection: Wear gloves resistant to chemicals, protective eyewear, lab coat or apron, and, if necessary, respiratory protection
Exposure Limits: Occupational exposure limits may be set in some jurisdictions due to acute and chronic toxicity
Appearance: White to pale yellow powder
Odor: Slightly pungent, aromatic
Solubility: Moderately soluble in water
Melting Point: Decomposes at high temperatures rather than displaying a sharp melting point
Stability: Reacts with strong oxidizers, sensitive to prolonged exposure to air and heat
Molecular Weight: 222.22 g/mol
Chemical Stability: Stable under recommended storage conditions with proper handling
Reactivity: Incompatible with oxidizing agents and acids, can undergo hazardous decomposition under fire conditions
Hazardous Polymerization: Unlikely under normal laboratory or industrial settings
Acute Toxicity: Harmful or fatal if swallowed, inhaled, or in contact with skin; symptoms can include nausea, vomiting, headache, dizziness, weakness
Chronic Toxicity: Repeated exposure can damage blood cells, liver, kidneys; links to increased risk of cancer in animal studies
Cancer Risk: Classified as possibly carcinogenic based on animal data and its chemical properties related to other known hazards
Environmental Hazards: Harmful to aquatic organisms and may cause long-term adverse effects in the aquatic environment
Persistence: Can remain present in soil and water for extended periods
Bioaccumulation: Low potential for biological accumulation within aquatic species based on its chemical structure and behavior
Methods of Disposal: Collect and dispose of through a licensed chemical waste disposal service; avoid pouring down drains or mixing with regular trash
Precautions During Disposal: Use appropriate personal protective equipment and follow regulatory requirements to avoid environmental releases or human exposure
UN Number: Regulated as hazardous material for ground and air transport
Hazard Class: Toxic solid, organic
Shipping Precautions: Ship in tightly sealed, labeled containers, conforming to international transport regulations to limit risk of spills or exposure
Packing Group: Assigned based on concentration and hazard level
Workplace Standards: Subject to workplace chemical safety regulations, including labeling, handling, and exposure guidelines
Environmental Controls: Disposal and emissions governed by environmental protection agencies or similar bodies
Import/Export Controls: Moves across international borders as a regulated substance; require permits and declarations for customs clearance
