2-((4-Chloro-5-oxo-1,2,5,6-tetrahydro-[1,1'-biphenyl]-3-yl)amino)benzoic acid CAS 937604-84-7 chemical structure

Description

The occurrence of 2-((4-Chloro-5-oxo-1,2,5,6-tetrahydro-[1,1'-biphenyl]-3-yl)amino)benzoic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((4-Chloro-5-oxo-1,2,5,6-tetrahydro-[1,1'-biphenyl]-3-yl)amino)benzoic acid (CAS 937604-84-7), molecular formula C19H16ClNO3 and molecular weight 341.79 g/mol, is a CATO reference standard with documented purity and traceability.

2-((4-Chloro-5-oxo-1,2,5,6-tetrahydro-[1,1'-biphenyl]-3-yl)amino)benzoic acid (C19H16ClNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
