Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-bromo-5-methoxy-2-methyl-1,3-benzoxazole.
CATO supplies 6-bromo-5-methoxy-2-methyl-1,3-benzoxazole (CAS 869561-95-5), a certified reference material (molecular formula C9H16BrNO2, MW 250.13 g/mol) for analytical method development and quality control.
The molecular framework of 6-bromo-5-methoxy-2-methyl-1,3-benzoxazole (C9H16BrNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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.
