Prothiophos CAS 34643-46-4 chemical structure

Description

CATO manufactures Prothiophos 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.

CATO supplies Prothiophos (CAS 34643-46-4), a certified reference material (molecular formula C11H15Cl2O2PS2, MW 345.25 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H15Cl2O2PS2, Prothiophos contains a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 345.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
