Chemical Structure
Description
CATO supplies (R)-2-Amino-4-bromobutanoic acid hydrobromide (CAS 177472-34-3), a certified reference material (molecular formula C4H8BrNO2HBr, MW 262.93 g/mol) for analytical method development and quality control.
The molecular framework of (R)-2-Amino-4-bromobutanoic acid hydrobromide (C4H8BrNO2HBr) 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.
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.
As a certified reference material (CRM), (R)-2-Amino-4-bromobutanoic acid hydrobromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
