About 4-Aminoantipyrine, 95%+

Listed under CAS 83-07-8, 4-Aminoantipyrine is an enzyme / protein reagent available from Vaqora Chemicals in Synthesis grade at a purity of ≥95%. Formula C11H13N3O, molecular weight 203.24 g/mol. Its systematic (IUPAC) name is 4-amino-1,5-dimethyl-2-phenylpyrazol-3-one. Alternative names: 4-AA and 4-Aminophenazone.

The material typically appears as powder or crystalline powder or chunks. Literature values give a melting point of 105-110 °C. Store it at room temperature in a dry place, in a tightly closed container. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for enzymatic assays, enzyme inhibition studies and protein research. Buyers come mainly from academic and industrial research and diagnostics and biotechnology.

Standard pack sizes are 25 g, 100 g, 500 g and 1 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
