O-Ethyl O-Phenyl S-Propyl Phosphorothioate CAS 40626-35-5

Description

Compared with other compounds in its class, the molecular weight of 260.29 g/mol gives O-Ethyl O-Phenyl S-Propyl Phosphorothioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

O-Ethyl O-Phenyl S-Propyl Phosphorothioate (CAS 40626-35-5) is a high-purity analytical reference standard with the molecular formula C11H17O3PS and a molecular weight of 260.29 g/mol.

O-Ethyl O-Phenyl S-Propyl Phosphorothioate (C11H17O3PS) contains a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), O-Ethyl O-Phenyl S-Propyl Phosphorothioate 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.
