Chemical Structure

Diisopropyl methylphosphonate CAS 1445-75-6 chemical structure

Description

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.

Diisopropyl methylphosphonate (CAS 1445-75-6), molecular formula C7H17O3P and molecular weight 180.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Diisopropyl methylphosphonate (C7H17O3P) 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.

As a certified reference material (CRM), Diisopropyl methylphosphonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
