[1,1':3',1''-Terphenyl]-4,4''-dicarboxylicacid,5'-(4-carboxy-3,5-difluorophenyl)-3,3'',5,5''-tetrafluoro- CAS 1660960-33-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [1,1':3',1''-Terphenyl]-4,4''-dicarboxylicacid,5'-(4-carboxy-3,5-difluorophenyl)-3,3'',5,5''-tetrafluoro-.

CATO supplies [1,1':3',1''-Terphenyl]-4,4''-dicarboxylicacid,5'-(4-carboxy-3,5-difluorophenyl)-3,3'',5,5''-tetrafluoro- (CAS 1660960-33-7), a certified reference material (molecular formula C27H12F6O6, MW 546.37 g/mol) for analytical method development and quality control.

Structurally, [1,1':3',1''-Terphenyl]-4,4''-dicarboxylicacid,5'-(4-carboxy-3,5-difluorophenyl)-3,3'',5,5''-tetrafluoro- (C27H12F6O6) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 546.37 g/mol, it falls into the moderately-high-molecular-weight range. 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.
