Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 282.38 g/mol gives 12-Mercaptododecylphosphonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
12-Mercaptododecylphosphonic acid (CAS 159239-33-5) is a high-purity analytical reference standard with the molecular formula C12H27O3PS and a molecular weight of 282.38 g/mol.
Structurally, 12-Mercaptododecylphosphonic acid (C12H27O3PS) contains a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 282.38 g/mol, it falls into the medium-molecular-weight range. 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), 12-Mercaptododecylphosphonic acid 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.
