Chemical Structure

Trimethylolpropane Phosphite CAS 824-11-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 162.12 g/mol gives Trimethylolpropane Phosphite distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Trimethylolpropane Phosphite (CAS 824-11-3), molecular formula C6H11O3P and molecular weight 162.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Trimethylolpropane Phosphite (C6H11O3P) is characterized by a phosphonate 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Trimethylolpropane Phosphite 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.
