Chemical Structure

Isopropyl phosphite CAS 691-96-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 166.16 g/mol gives Isopropyl phosphite distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Isopropyl phosphite (CAS 691-96-3), a certified reference material (molecular formula C6H15O3P, MW 166.16 g/mol) for analytical method development and quality control.

Structurally, Isopropyl phosphite (C6H15O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 166.16 g/mol, it falls into the medium-molecular-weight range.

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.

As a certified reference material (CRM), Isopropyl phosphite 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.
