The occurrence of Methamidophos-N-Methyl is closely related to an amide group, a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methamidophos-N-Methyl (CAS 28167-49-9), molecular formula C3H10NO2PS and molecular weight 155.16 g/mol, is a CATO reference standard with documented purity and traceability.
Methamidophos-N-Methyl (C3H10NO2PS) contains an amide group, a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures Methamidophos-N-Methyl 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.
