Chemical Structure

1-Diethoxyphosphoryloctadecane CAS 16165-72-3 chemical structure

Description

As a certified reference material (CRM), 1-Diethoxyphosphoryloctadecane 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.

1-Diethoxyphosphoryloctadecane (CAS 16165-72-3), molecular formula C22H47O3P and molecular weight 390.58 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1-Diethoxyphosphoryloctadecane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
