About Magneson I, GR indicator

Magneson I (CAS 74-39-5) is a biological stain offered by Vaqora Chemicals in AR grade. With the molecular formula C12H9N3O4, it has a molar mass of 259.22 g/mol. The IUPAC name is 4-[(4-nitrophenyl)diazenyl]benzene-1,3-diol. It is also known as Azoviolet or 4-(4-Nitrophenylazo)resorcinol.

It is supplied as a powder. 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.

It is commonly used for histology and cytology staining, microscopy, clinical laboratories and indicator for titrations. Buyers come mainly from academic and industrial research, diagnostics and biotechnology and textiles and dyeing.

We offer Magneson I in 1 g, 25 g, 100 g and 4 x 25 kg packs with a batch-specific COA, and ship to customers worldwide.
