Chemical Structure

Dibutyl Phosphite CAS 1809-19-4 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.

CATO supplies Dibutyl Phosphite (CAS 1809-19-4), a certified reference material (molecular formula C8H19O3P, MW 194.21 g/mol) for analytical method development and quality control.

Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, Dibutyl Phosphite is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

As a certified reference material (CRM), Dibutyl 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.
