4­DIMETHYLAMINOBENZALDEHYDE ((CH3)2NC6H4CHO)

SYNONYMS
None known.
CHARACTERISTICS
White, yellow or greenish­yellow combustible, crystalline powder.
INCOMPATIBILITY
Heating produces toxic fumes.
Dimethylaminobenzaldehyde is incompatible with oxidising materials with which it has a vigorous reaction.
HEALTH HAZARD DATA
A combustible substance that is an eye and respiratory tract irritant. It is regarded as being of low toxicity when ingested. This substance will stain skin.
HANDLING and GENERAL PRECAUTIONS
Avoid eye contact.
Avoid inhalation of the powder.
Avoid ingestion.
Keep away from heat or naked flames.
Keep away from oxidising materials.
Wash hands thoroughly after handling.
Wear protective clothing to avoid skin or eye contact and inhalation. A long sleeved laboratory coat or gown, rubber gloves, safety goggles and a face mask as a minimum standard.
TREATMENTS
Skin ­ immediately wash the affected area with soap or mild detergent and large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes).
Eyes ­ immediately wash the affected eye with large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). If irritation persists seek medical attention.

Ingestion ­ wash out the mouth thoroughly with water and give water to drink. Seek medical advice.
STORAGE
Store in a cool, dry atmosphere away from heat or naked flames.
DISPOSAL
WEAR:
Rubber gloves, self contained breathing apparatus and laboratory coat.
SPILLS:
Eliminate all sources of ignition and flammables.
Small: absorb on a paper towel. Evaporate in fume hood and burn the paper.
Large: cover with sodium bisulphite. Add a small amount of water and mix. Scoop into a large beaker. Discharge to sewer with a large excess of water. Wash the spill site with a soapy solution.
PACKAGE LOTS: Either
1 Absorb on vermiculite. Burn in an open pit or open incinerator.
2 Dissolve in a flammable solvent (such as acetone or benzene). Spray into the fire box of an incinerator equipped with an afterburner.
