Chemical Structure
Description
CATO manufactures 1,3-Phenylene tetraethyl bis(phosphate) 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.
1,3-Phenylene tetraethyl bis(phosphate) (CAS 109592-16-7), molecular formula C14H24O8P2 and molecular weight 382.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3-Phenylene tetraethyl bis(phosphate) (C14H24O8P2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
