Chemical Structure

Triisopropyl phosphate CAS 513-02-0 chemical structure

Description

The occurrence of Triisopropyl phosphate is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Triisopropyl phosphate (CAS 513-02-0), molecular formula C9H21O4P and molecular weight 224.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Triisopropyl phosphate (C9H21O4P) 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.

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 phosphate 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.
