Chemical Structure
Description
As a certified reference material (CRM), S-(2-(Butylthio)ethyl) O-ethyl cyclohexylphosphonothioate 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.
S-(2-(Butylthio)ethyl) O-ethyl cyclohexylphosphonothioate (CAS 63811-80-3) is a high-purity analytical reference standard with the molecular formula C14H29O2PS2 and a molecular weight of 324.48 g/mol.
S-(2-(Butylthio)ethyl) O-ethyl cyclohexylphosphonothioate (C14H29O2PS2) contains a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
