Chemical Name: N,N-Dimethylisopropanolamine
Synonyms: 1-(Dimethylamino)-2-propanol
Chemical Formula: C5H13NO
CAS Number: 96-80-0
Recommended Usage: Commonly used in chemical synthesis, water treatment, ink production, and surfactant formulation across various industrial fields.
Physical Appearance: This chemical shows up as a clear to light yellow liquid, with a noticeable ammonia-like odor and mixes easily with water.
GHS Classification: Eye irritation (Category 2A), Skin irritation (Category 2)
Potential Health Hazards: Causes eye and skin irritation with direct contact. Inhaling vapors may cause respiratory discomfort, coughing, and throat irritation. Prolonged exposure increases risk of more severe irritation.
Warning Symbols: Exclamation mark (Irritant)
Routes of Exposure: Eyes, skin, inhalation, ingestion
Precautionary Statements: Avoid breathing mist or vapor. Wear protective gloves, eye protection, and clothing. Wash hands thoroughly after handling. Avoid direct contact with eyes and skin.
Chemical: N,N-Dimethylisopropanolamine
Concentration: More than 99% active ingredient in most industrial containers
Impurities: Trace water, minor alkanolamine residues
Inhalation: Move affected person into fresh air, keep comfortable and watch for ongoing irritation. Seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing and wash area with soap and water for several minutes. Get medical help if irritation continues.
Eye Contact: Rinse eyes gently with water for several minutes, lifting the eyelids. Immediate medical attention recommended.
Ingestion: Rinse mouth thoroughly and do not induce vomiting without medical advice. Call for poison control or healthcare support.
Suitable Extinguishing Media: Use foam, dry chemical powder, carbon dioxide, or water spray.
Hazardous Combustion Products: Burns to form carbon oxides, nitrogen oxides, and potentially toxic vapors.
Protective Equipment: Wear full protective gear including self-contained breathing apparatus to protect against toxic fumes.
Special Hazards: Vapors may be harmful if inhaled or may concentrate in low-lying areas.
Personal Precautions: Use gloves, goggles, and chemical-resistant footwear. Avoid direct contact.
Spill Containment: Prevent spillage from reaching drains or open water. Use sand or inert absorbent to soak up liquid.
Cleanup Methods: Collect material with absorbent, place in container for disposal following local regulations. Ventilate spill area thoroughly.
Safe Handling Tips: Avoid inhaling vapors, wear personal protective equipment, do not eat, drink, or smoke in handling areas, wash hands thoroughly after work.
Storage Requirements: Keep in tightly closed containers in cool, dry, well-ventilated locations, away from direct sunlight, acids, oxidizing agents, and incompatible materials.
Incompatible Materials: Strong acids, strong oxidizers, reducing agents
Special Storage Cautions: Keep containers tightly sealed to avoid moisture absorption and maintain chemical stability.
Engineering Controls: Use exhaust ventilation or other engineering controls to keep airborne levels below exposure limits.
Personal Protective Equipment (PPE): Wear splash goggles, chemical-resistant gloves, lab coats, and face shields where splashes might occur.
Respiratory Protection: For vapor or aerosol formation, use appropriate respirators.
Hygiene Measures: Wash hands, face, and exposed skin after use. Regularly inspect PPE for wear.

Boiling Point: Around 161°C (321°F)
Melting Point: Approximately -55°C (-67°F)
Flash Point: 74°C (165°F) (Closed cup)
Solubility: Completely soluble in water, alcohols
Vapor Density (Air=1): Slightly heavier than air
Viscosity: Moderate
Chemical Stability: Stable under normal temperatures and pressures
Possibility of Hazardous Reactions: Reacts with strong acids, oxidizers, and materials that react with amines
Hazardous Decomposition Products: Toxic ammonia, nitrogen oxides, carbon monoxide, carbon dioxide
Conditions to Avoid: Extreme heat, open flame, mixing with incompatible materials
Acute Oral Toxicity: Toxicity is moderate; accidental ingestion can cause nausea, vomiting, abdominal pain
Skin Irritation: Can cause strong irritation, redness, prolonged exposure amplifies symptoms
Eye Irritation: Serious eye damage possible
Inhalation Effects: Dizziness, headaches, throat irritation may follow from excessive exposure
Sensitization: No evidence of allergic skin reaction under normal use*
Chronic Effects: Repeated skin contact may cause dermatitis and dryness
Environmental Impact: Harmful to aquatic organisms, especially fish and invertebrates in concentrated spills
Persistence and Degradability: Biodegradable under aerobic conditions
Bioaccumulation: Low potential for bioconcentration
Mobility: Highly mobile in water due to solubility
Waste Disposal Methods: Dispose of in accordance with local, regional, and national environmental legislation. Incineration or professional chemical disposal highly recommended. Do not pour into surface water or municipal sewers.
UN Classification: Not classified as hazardous for most modes of transport in standard packaging concentrations
Shipping Name: Chemical, Liquid, NOS (N,N-Dimethylisopropanolamine)
Packaging Instructions: Use tightly sealed, chemical-resistant containers; protect from damage and label containers clearly.
US Regulations: Regulated under OSHA for hazardous substances with required hazard communication programs. Listed on TSCA inventory. No threshold planning quantity under SARA Title III.
EU Regulations: Classified as hazardous under CLP. Requires safety labeling, use restrictions, and risk mitigation for workers.
International: Found in several inventories globally including Canada’s DSL, Australia’s AICS, and Japan’s ENCS.
