2-[[4-[(2'-Chloro[1,1'-biphenyl]-3-yl)methoxy]phenyl]sulfonyl]acetic Acid CAS 2102196-57-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[[4-[(2'-Chloro[1,1'-biphenyl]-3-yl)methoxy]phenyl]sulfonyl]acetic Acid.

2-[[4-[(2'-Chloro[1,1'-biphenyl]-3-yl)methoxy]phenyl]sulfonyl]acetic Acid (CAS 2102196-57-4), molecular formula C21H17ClO5S and molecular weight 416.87 g/mol, is a CATO reference standard with documented purity and traceability.

2-[[4-[(2'-Chloro[1,1'-biphenyl]-3-yl)methoxy]phenyl]sulfonyl]acetic Acid (C21H17ClO5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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).

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.
