Chemical Structure
Description
Didodecyl phosphonate (CAS 21302-09-0) is a high-purity analytical reference standard with the molecular formula C24H51O3P and a molecular weight of 418.63 g/mol.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, Didodecyl phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.63 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.
CATO manufactures Didodecyl phosphonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
