Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 331.52 g/mol gives (Z)-Dimethylvinphos distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(Z)-Dimethylvinphos (CAS 67628-93-7), molecular formula C10H10Cl3O4P and molecular weight 331.52 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (Z)-Dimethylvinphos (C10H10Cl3O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 331.52 g/mol, it falls into the moderately-high-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), (Z)-Dimethylvinphos 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.
