CAS 305-80-6

Diazotized sulfanilic acid

Description:

Diazotized sulfanilic acid, with the CAS number 305-80-6, is an important chemical compound in the field of organic chemistry, particularly in the synthesis of azo dyes. It is derived from sulfanilic acid, which is an aromatic amine. The compound is characterized by the presence of a diazo group (-N=N-) attached to the sulfanilic acid structure, which enhances its reactivity and utility in various chemical reactions. Diazotized sulfanilic acid is typically a yellow to orange solid, soluble in water, and exhibits stability under acidic conditions. It is sensitive to light and heat, which can lead to decomposition. This compound is primarily used in the preparation of azo dyes, where it acts as a coupling agent, reacting with other aromatic compounds to form vibrant colored products. Additionally, it plays a role in analytical chemistry, particularly in colorimetric assays. Safety precautions are necessary when handling this compound, as it can be hazardous if ingested or inhaled, and appropriate protective measures should be taken.
