Chemical Structure
Description
The occurrence of 2-(5-bromo-3-thienyl)acetic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(5-bromo-3-thienyl)acetic acid (CAS 1057217-28-3), molecular formula C6H9BrO2S and molecular weight 225.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(5-bromo-3-thienyl)acetic acid (C6H9BrO2S) is characterized by a sulfone group, 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.
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.
