About Crystal violet, ACS, for spectroscopy ≥90.00%

Crystal violet is a biological stain in ACS / Spectroscopy grade carrying the CAS registry number 548-62-9 with a typical assay of ≥90.00%. With the molecular formula C25H30ClN3, it has a molar mass of 408.0 g/mol. The IUPAC name is [4-[bis[4-(dimethylamino)phenyl]methylidene]cyclohexa-2,5-dien-1-ylidene]-dimethylazanium chloride. It is also known as gentian violet or methylrosanilinium chloride.

It is supplied as a crystalline solid. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, 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.

Available in 10 g, 25 g, 100 g and 1 kg packs, Crystal violet is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
