10127-36-3 1,3-Diamino-7-(diethylamino)-8-methylphenoxazin-5-ium chloride Phenoxazin-5-ium, 1,3-diamino-7-(diethylamino)-8-methyl-, chloride Phenoxazin-5-ium, 1,3-diamino-7-(diethylamino)-8-methyl-, chloride (1:1) C.I. 51010 Brilliant Cresyl Blue BB EINECS 233-358-3 (CAS 10127-36-3) is a high-purity analytical reference standard with the molecular formula C17H21N4OCl and a molecular weight of 332.83 g/mol.
The molecular framework of 10127-36-3 1,3-Diamino-7-(diethylamino)-8-methylphenoxazin-5-ium chloride Phenoxazin-5-ium, 1,3-diamino-7-(diethylamino)-8-methyl-, chloride Phenoxazin-5-ium, 1,3-diamino-7-(diethylamino)-8-methyl-, chloride (1:1) C.I. 51010 Brilliant Cresyl Blue BB EINECS 233-358-3 (C17H21N4OCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
