Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Bromo-2-[2-(4-methoxyphenyl)ethenyl]quinoline-4-carboxylic acid (CAS 1421636-31-8), molecular formula C19H14BrNO3 and molecular weight 384.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-2-[2-(4-methoxyphenyl)ethenyl]quinoline-4-carboxylic acid (C19H14BrNO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
