About Crystal violet, GR

Vaqora Chemicals supplies Crystal violet (AR grade), a biological stain registered under CAS number 548-62-9, specified at 96–100% purity. Its molecular formula is C25H30ClN3 and its molecular weight is 408.0 g/mol. The IUPAC name is [4-[bis[4-(dimethylamino)phenyl]methylidene]cyclohexa-2,5-dien-1-ylidene]-dimethylazanium chloride. Common synonyms include Brilliant Violet 58 and gentian violet.

The material typically appears as a crystalline powder. Key physical data: a melting point of 189-194 °C. Store in a tightly closed container in a cool, dry and well-ventilated place. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span histology and cytology staining, microscopy, clinical laboratories and biological staining. Buyers come mainly from academic and industrial research, diagnostics and biotechnology and textiles and dyeing.

Vaqora Chemicals supplies Crystal violet in 25 g, 100 g, 1 kg and 4 x 25 kg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
