A further Corydalis alkaloid, coramine has been obtained from C. pseudoadunca
M. Pop. It forms colourless needles from EtOH and is optically active with a
specific rotation of [α]D - 391 ° (c 0.2, MeOH). Both the hydrochloride, m.p.
216-9°C and the hydrobromide, m.p. 223-6°C have been described.
clear colorless to yellow liquid

ChEBI: Nikethamide is a pyridinecarboxamide. It is functionally related to a nicotinamide.
Clear light yellow viscous liquid or crystalline solid. Slightly bitter taste followed by a faint sensation of the warmth.
N,N-DIETHYLNICOTINAMIDE is incompatible with sodium carbonate solutions which cause precipitation. .
ACUTE/CHRONIC HAZARDS: When heated to decomposition N,N-DIETHYLNICOTINAMIDE emits toxic fumes.
N,N-DIETHYLNICOTINAMIDE is combustible.
Poison by ingestion,
