Chemical Structure
Description
(12-Chlorododecyl)phosphonic acid (CAS 1049677-20-4) is a high-purity analytical reference standard with the molecular formula C12H26ClO3P and a molecular weight of 284.76 g/mol.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (12-Chlorododecyl)phosphonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.76 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.
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 manufactures (12-Chlorododecyl)phosphonic acid 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.
