Chemical Name: Diethylaminocyanide
Synonyms: N,N-Diethylcyanamide
CAS Number: 628-96-6
Appearance: Often turns up as a colorless to pale yellow liquid, with an odor that hints at ammonia or fish.
Uses: This compound doesn’t come up in everyday talk, but it pops up in organic synthesis, especially when chemists chase after cyano-substituted structures or use it as a building block for all sorts of other specialty chemicals and intermediates.
Main Hazards: Skin and respiratory tract irritation, with enough volatility to spark short-term headaches or dizziness in poorly ventilated workplaces. Inhalation of vapors leaves you nauseous, groggy, or short of breath. Spills on the skin burn or trigger redness. Soaking up this chemical over time puts workers at risk for long-term health effects, especially around the eyes, kidneys, or liver.
Labels: Flammable liquid, acute toxicity, health hazard
Routes of Entry: Inhalation, skin contact, ingestion
Component: Diethylaminocyanide
Concentration: Typically close to 100 percent in pure stocks, with impurities showing up only in trace amounts due to synthesis leftovers.
Impurities: Trace amines or unreacted precursor chemicals if produced in-house.
Eye Contact: Rinse eyes gently but quickly for at least 15 minutes under running water, eyelids wide open—don’t rub.
Skin Contact: Peel off tainted clothing. Wash the area with soap and plenty of water. Medical attention matters if skin turns red or blisters.
Inhalation: Drag the person outside for fresh air. Give oxygen if breathing feels strained. Medical care is critical if breathing does not return to normal soon.
Ingestion: Rinsing out the mouth might help, but don’t force vomiting. Call medical pros right away, as swallowing this chemical can be dangerous.
Suitable Extinguishing Media: Dry chemical powder, foam, or carbon dioxide knocks down most fires. Water does the job for small splashes, but risks spreading contamination.
Hazardous Combustion Products: Fires break Diethylaminocyanide down into fumes, possibly hydrogen cyanide and nitrogen oxides, both toxic.
Special Precautions for Firefighters: Full-face respirators and protective suits are a must. Stay upwind to steer clear of nasty smoke. The flash point comes in low enough to treat this as a flammable risk.
Personal Precautions: Evacuate the area at once. Wear gloves, goggles, and a chemical apron to avoid direct contact. Avoid breathing in vapors.
Environmental Precautions: Keep away from drains or rivers. Even a small spill can cause trouble for aquatic life.
Spill Cleanup: Absorb small spills with sand or earth. Use appropriate containers to scoop up tainted material. Larger releases call for trained hazmat teams.
Safe Handling: Ventilation cuts the odds of buildup—no one needs to breathe extra fumes. Store only in closed, clearly labeled containers. Don’t eat or drink in work areas.
Storage Conditions: Keep containers in a cool, dry place, away from direct sunlight or open flames. Segregate from strong acids, oxidizers, or bases.
Engineering Controls: Fume hoods do the heavy lifting when it comes to catching volatile vapors indoors. General room ventilation helps as a backup.
Personal Protective Equipment (PPE): Chemical-resistant gloves and safety goggles should always be on hand. Lab coats or aprons serve as frontline defenses for skin and street clothes.
Respiratory Protection: Cartridge respirators or air-supplied masks give the best coverage for airborne vapors, especially during cleanup.
Form: Liquid, colorless to yellow
Odor: Unpleasant, amine-like
Boiling Point: Ranges near 178-180°C
Melting Point: Below room temperature, typically around -35°C
Solubility: Not much favor for water, but dissolves readily in organic solvents like ether or alcohol.
Vapor Pressure: Moderate, enough to pose inhalation risks at room temp
Density: About 0.89 g/cm³
Chemical Stability: Stays together under proper storage, but heat, flame, or strong light trigger decomposition.
Conditions to Avoid: Sparks, open flame, sources of heat
Incompatibility: Smashes up in the presence of acids, oxidizers, or strong bases.
Hazardous Decomposition: Hydrolysis or burning can toss off hydrogen cyanide and toxic nitrogen-based gases.
Acute Toxicity: Short-term exposure irritates the eyes, skin, lungs, and gut. Breathing in much vapor leads to nausea, headaches, or lightheadedness.
Chronic Exposure: Repeated or long exposures risk kidney, liver, or neurological damage. Peripheral numbness in fingers or toes can show up with extended handling.
Sensitization: Reports of skin sensitization are rare, but caution with repeated use remains crucial.
Mobility: Stays around soils and leaches slowly due to moderate volatility and water insolubility.
Aquatic Toxicity: Harmful to fish and insects at low concentrations. A release wipes out local populations in small ponds or streams.
Persistence: The molecule does not break down quickly in the environment, lingering and building up over time.
Preferred Disposal Methods: Expert chemical waste disposal by incineration in controlled conditions minimizes risk. Sewers or general rubbish bins don’t cut it; labs and facilities bring the waste to hazardous material handlers.
Contaminated Packaging: Empty bottles or drums need a similar fate. No rinsing into sinks or water lines.
Transport Hazards: Diethylaminocyanide counts as a regulated flammable liquid, often flagged at border crossings or during shipping by truck, air, or sea. Leaks raise eyebrows because of the potential for acute poisoning and fire.
Packing Group: Usually assigned to a packing group with strict containment and labeling rules.
Workplace Controls: Occupational safety rules tend to set sharp exposure limits. Regular air monitoring in labs keeps levels below dangerous thresholds.
Labeling: Containers get hazard labels as required by chemical safety agencies. Signs in storage areas remind staff about the fire and health risks.
Reporting Requirements: Large spills or accidental releases often require notification of regulatory bodies in the region. Tracking and documentation help meet both legal and insurance needs.
