Chemical Name: 4-(Dimethylamino)cinnamaldehyde
Common Synonyms: DMAC, p-Dimethylaminocinnamaldehyde
Chemical Formula: C11H13NO
Appearance: Yellow to orange powder or crystalline solid
Use: Reagent in chemical analysis, often found in laboratories testing for flavonoids or alkaloids
Hazard Classification: May cause skin and eye irritation, possible respiratory irritant
Signal Words: Warning
Health Hazards: Prolonged or repeated skin contact can trigger irritation; inhalation of dust might cause discomfort in the airways; ingestion carries toxicity risk
Environmental Hazards: Potential impact on aquatic life if released in large amounts
Main Ingredient: 4-(Dimethylamino)cinnamaldehyde
Concentration: Pure, no significant impurities expected in lab-grade material
Inhalation: Move to fresh air, get medical help if breathing becomes difficult
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water
Eye Contact: Rinse immediately with plenty of water, seek medical advice if irritation remains
Ingestion: Rinse mouth, drink water, do not induce vomiting, consult clinician
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or CO2 for smaller fires
Hazards: Produces toxic fumes under extreme heat—potential for nitrogen oxides, carbon monoxide/dioxide
Protective Equipment: Firefighters need self-contained breathing apparatus, full gear
Personal Precautions: Avoid breathing dust, prevent skin or eye contact; use dust mask and gloves
Methods: Sweep or scoop up without creating dust, place in container for disposal
Environmental Precautions: Avoid release to waterways or soil—contain spills where possible
Safe Handling: Use in a well-ventilated area, avoid direct contact, never eat, drink, or smoke while handling
Storage Conditions: Store in cool, dry, tightly closed containers, segregate from incompatible substances such as strong oxidizers or acids
Engineering Controls: Local ventilation or extraction systems recommended
Eye Protection: Safety goggles
Skin Protection: Protective gloves (nitrile or latex)
Respiratory Protection: NIOSH-approved dust mask or equivalent for dusty conditions
Hygiene: Wash hands after use, do not touch face while handling
Physical State: Solid, crystalline
Color: Yellow to orange
Odor: Aromatic, slightly amine-like
Melting Point: 70-73°C
Solubility: Slight in water, better in ethanol and organics
Boiling Point: Not typically measured due to decomposition
Other Properties: Stable under ordinary temperature and pressure if kept dry and sealed
Chemical Stability: Stable unless exposed to strong acids, oxidizing agents, extreme heat
Reactivity: Can undergo reactions with acids or oxidizers; no violent reactivity under typical lab use
Hazardous Decomposition: Could produce toxic gases in fire
Possible Effects: Irritation to skin, eyes, respiratory system; ingestion causes gastrointestinal discomfort, may have harmful systemic effects in high doses
Long-Term Exposure: Combined data is scarce, most advice draws from structurally related aldehydes or aromatic amines
Special Populations: Take extra caution around those with preexisting conditions, particularly respiratory or skin sensitivities
Aquatic Toxicity: Some risk exists for aquatic life; proper lab disposal helps minimize pollution
Bioaccumulation: Not expected to bioaccumulate significantly in the environment
Persistence: Tends to break down in the presence of microbes or light over time, but disposal in regular waste streams remains inappropriate
Waste Treatment: Dispose of as hazardous waste according to city or institutional regulations
Keep Out of Sewer: Never pour down drain or toilet; use sealed labeling and hand off to disposal contractor
Container Disposal: Triple rinse and puncture before discarding, or deliver empty bottles as hazardous waste
Packaging: Ship in tightly sealed, properly labeled containers
Precautions: Prevent breakage or spillage; handle as a laboratory chemical, not household goods
Local Law: Classification varies by region, but care in labeling prevents hazardous mixing or unmarked release
Chemical Inventories: Registered in many national chemical inventories used for research and industrial chemicals
Restrictions: Certain jurisdictions might require reporting on import or use amounts
Workplace Rules: Standard lab safety protocols offer the best protection; training for new users remains key in any academic or industrial setting
