Triisopropyl phosphite CAS 116-17-6 chemical structure

Description

Triisopropyl phosphite (CAS 116-17-6) is a high-purity analytical reference standard with the molecular formula C9H21O3P and a molecular weight of 208.24 g/mol.

Structurally, Triisopropyl phosphite (C9H21O3P) 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 208.24 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), Triisopropyl 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.
