About Alizarine complexone

Alizarine complexone (CAS 3952-78-1) is an indicator offered by Vaqora Chemicals. Formula C19H15NO8, molecular weight 385.3 g/mol. The IUPAC name is 2-[carboxymethyl-[(3,4-dihydroxy-9,10-dioxoanthracen-2-yl)methyl]amino]acetic acid. Alternative names: Alizarin Fluorine Blue and Alizarine Fluorine Blue.

It is supplied as a brown powder. Key physical data: a melting point of 183 - 187 °C. Store in a tightly closed container in a cool, dry and well-ventilated place. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include titration end-point detection, pH determination and analytical testing. Buyers come mainly from academic and industrial research.

Standard pack sizes are 1 g, 5 g, 5 x 100 g and 5 x 1 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
