Chemical Structure
Description
Owing to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-3',5'-dimethoxy-[1,1'-biphenyl]-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-Chloro-3',5'-dimethoxy-[1,1'-biphenyl]-4-carboxylic acid (CAS 1261992-00-0) is a high-purity analytical reference standard with the molecular formula C15H13ClO4 and a molecular weight of 292.71 g/mol.
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.
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.
