Chemical Structure

P,P’’-[(1,2-Phenylene)bis(methylene)]bisphosphonic Acid P,P,P’’,P’’-tetraethyl ester CAS 42092-05-7 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 P,P’’-[(1,2-Phenylene)bis(methylene)]bisphosphonic Acid P,P,P’’,P’’-tetraethyl ester.

P,P’’-[(1,2-Phenylene)bis(methylene)]bisphosphonic Acid P,P,P’’,P’’-tetraethyl ester (CAS 42092-05-7) is a high-purity analytical reference standard with the molecular formula C16H28O6P2 and a molecular weight of 378.34 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, P,P’’-[(1,2-Phenylene)bis(methylene)]bisphosphonic Acid P,P,P’’,P’’-tetraethyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 378.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 P,P’’-[(1,2-Phenylene)bis(methylene)]bisphosphonic Acid P,P,P’’,P’’-tetraethyl ester 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.
