Acid Chloride

Organic compounds derived from carboxylic acids by replacing the hydroxyl group with a chlorine atom, making them highly reactive acylating agents.

Anhydride

A compound formed from another compound by the removal of a molecule of water; commonly associated with carboxylic acid anhydrides in organic chemistry.

Nitrile

Organic compounds that contain a cyano group (-C≡N) attached to an alkyl group, used in the manufacture of rubbers, resins, and pharmaceuticals.

Amide

Organic compounds characterized by a carbonyl group attached to a nitrogen atom, often found in proteins and other important biological molecules.
