Chemical Structure
Description
The occurrence of 8-((4-Amino-3-nitrophenyl)diazenyl)-7-hydroxy-N,N,N-trimethylnaphthalen-2-aminium Chloride (Technical Grade) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 8-((4-Amino-3-nitrophenyl)diazenyl)-7-hydroxy-N,N,N-trimethylnaphthalen-2-aminium Chloride (Technical Grade) (CAS 68391-32-2), a certified reference material (molecular formula C19H20N5O3Cl, MW 401.85 g/mol) for analytical method development and quality control.
The molecular framework of 8-((4-Amino-3-nitrophenyl)diazenyl)-7-hydroxy-N,N,N-trimethylnaphthalen-2-aminium Chloride (Technical Grade) (C19H20N5O3Cl) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
