[1,1':3',1''-Terphenyl]-4,4''-dicarboxylic acid CAS 13215-72-0

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''-dicarboxylic acid.

CATO supplies [1,1':3',1''-Terphenyl]-4,4''-dicarboxylic acid (CAS 13215-72-0), a certified reference material (molecular formula C20H14O4, MW 318.32 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, [1,1':3',1''-Terphenyl]-4,4''-dicarboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), [1,1':3',1''-Terphenyl]-4,4''-dicarboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
