3'-Fluoro-2,4'-dimethyl-[1,1'-biphenyl]-4-carboxylic acid CAS 1261939-39-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3'-Fluoro-2,4'-dimethyl-[1,1'-biphenyl]-4-carboxylic acid.

CATO supplies 3'-Fluoro-2,4'-dimethyl-[1,1'-biphenyl]-4-carboxylic acid (CAS 1261939-39-2), a certified reference material (molecular formula C15H13FO2, MW 244.26 g/mol) for analytical method development and quality control.

3'-Fluoro-2,4'-dimethyl-[1,1'-biphenyl]-4-carboxylic acid (C15H13FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
