Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-amino-7-(diethylamino)-2-methylphenoxazin-5-ium tetrachlorozincate(II) 51716-96-2 Brilliant cresyl blue (CAS 51716-96-2) is a high-purity analytical reference standard with the molecular formula C17H20N3OCH3Cl4Zn and a molecular weight of 504.58 g/mol.
The molecular framework of 3-amino-7-(diethylamino)-2-methylphenoxazin-5-ium tetrachlorozincate(II) 51716-96-2 Brilliant cresyl blue (C17H20N3OCH3Cl4Zn) is characterized by a salt form, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 3-amino-7-(diethylamino)-2-methylphenoxazin-5-ium tetrachlorozincate(II) 51716-96-2 Brilliant cresyl blue under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
