Chemical Structure
Description
Dioctyl phenylphosphonate (CAS 1754-47-8) is a high-purity analytical reference standard with the molecular formula C22H45O3P and a molecular weight of 388.56 g/mol.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, Dioctyl phenylphosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.56 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.
As a certified reference material (CRM), Dioctyl phenylphosphonate 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.
