5,5'-(Anthracene-9,10-diylbis(ethyne-2,1-diyl))diisophthalic acid CAS 1337923-87-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,5'-(Anthracene-9,10-diylbis(ethyne-2,1-diyl))diisophthalic acid.

5,5'-(Anthracene-9,10-diylbis(ethyne-2,1-diyl))diisophthalic acid (CAS 1337923-87-1), molecular formula C34H18O8 and molecular weight 554.50 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 5,5'-(Anthracene-9,10-diylbis(ethyne-2,1-diyl))diisophthalic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 554.50 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.

CATO manufactures 5,5'-(Anthracene-9,10-diylbis(ethyne-2,1-diyl))diisophthalic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
