Methyl 2-amino-2-(5-bromothiophen-3-yl)acetate hydrochloride CAS 2137481-21-9

Description

The occurrence of Methyl 2-amino-2-(5-bromothiophen-3-yl)acetate hydrochloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Methyl 2-amino-2-(5-bromothiophen-3-yl)acetate hydrochloride (CAS 2137481-21-9), a certified reference material (molecular formula C7H8BrNO2SHCl, MW 286.57 g/mol) for analytical method development and quality control.

Methyl 2-amino-2-(5-bromothiophen-3-yl)acetate hydrochloride (C7H8BrNO2SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
