Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 244.09 g/mol gives 3-((2-Bromophenyl)amino)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-((2-Bromophenyl)amino)propanoic acid (CAS 38470-20-1), molecular formula C9H10BrNO2 and molecular weight 244.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((2-Bromophenyl)amino)propanoic acid (C9H10BrNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.
