3'-Chloro-4-fluoro-[1,1'-biphenyl]-3-carboxylic acid CAS 1261933-47-4

Description

The occurrence of 3'-Chloro-4-fluoro-[1,1'-biphenyl]-3-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3'-Chloro-4-fluoro-[1,1'-biphenyl]-3-carboxylic acid (CAS 1261933-47-4), a certified reference material (molecular formula C13H8ClFO2, MW 250.65 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H8ClFO2, 3'-Chloro-4-fluoro-[1,1'-biphenyl]-3-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
