Chemical Structure

(11-Mercaptoundecyl)phosphonic acid CAS 156125-36-9 chemical structure

Description

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.

(11-Mercaptoundecyl)phosphonic acid (CAS 156125-36-9), molecular formula C11H25O3PS and molecular weight 268.35 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (11-Mercaptoundecyl)phosphonic acid (C11H25O3PS) 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 268.35 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.

CATO manufactures (11-Mercaptoundecyl)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.
