Pigment Red 57

CAS: 5858-81-1

Pigment Red 57 is a red organic pigment with a chemical structure that includes a conjugated double bond. It is used as a control agent in the cell culture industry, and has been shown to be an effective reaction solution for histamine levels. Pigment Red 57 has been synthesized by reacting methyl ethyl hydrochloric acid with glycol ester and fatty acid, which was then reacted with polymer particles. The reaction intermediates were analyzed using magnetic particles, which confirmed the presence of the desired product.
