Chemical Structure
Description
(1,2-Phenylenebis(methylene))bis(phosphonic acid) (CAS 42104-58-5), molecular formula C8H12O6P2 and molecular weight 266.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, (1,2-Phenylenebis(methylene))bis(phosphonic acid) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.12 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 (1,2-Phenylenebis(methylene))bis(phosphonic 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.
