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 2-(Aminooxy)-2-methylpropanoic acid hydrobromide.
CATO supplies 2-(Aminooxy)-2-methylpropanoic acid hydrobromide (CAS 40674-23-5), a certified reference material (molecular formula C4H9NO3HBr, MW 200.03 g/mol) for analytical method development and quality control.
The molecular framework of 2-(Aminooxy)-2-methylpropanoic acid hydrobromide (C4H9NO3HBr) 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.
