103-70-8

White crystalline solid.

FORMANILIDE(103-70-8) is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

This chemical may be sensitive to prolonged exposure to air. . Soluble in water.

SYMPTOMS: Exposure to this chemical may cause cyanosis, headache, dizziness, confusion, decreased blood pressure, convulsions and coma.

This chemical is probably combustible.

white or light yellow crystals or powder

ChEBI: A member of the class of formamides that is formamide in which one of the amino hydrogens is replaced by a phenyl group.
