Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies a-Bromophenylacetic acid 2-bromo-2-phenylacetic acid alpha-bromophenylacetic acid a-(bromo)phenylacetic acid dl-alpha-bromophenylacetic acid bromo-phenyl-acetic acid 4870-65-9 (CAS 4870-65-9), a certified reference material (molecular formula C8H13BrO2, MW 221.09 g/mol) for analytical method development and quality control.
The molecular framework of a-Bromophenylacetic acid 2-bromo-2-phenylacetic acid alpha-bromophenylacetic acid a-(bromo)phenylacetic acid dl-alpha-bromophenylacetic acid bromo-phenyl-acetic acid 4870-65-9 (C8H13BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
