1-(methoxymethyl)-3,5-dimethyl-1H-pyrazole-4-sulfonyl chloride (CAS 1803605-48-2), molecular formula C7H11ClN2O3S and molecular weight 238.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(methoxymethyl)-3,5-dimethyl-1H-pyrazole-4-sulfonyl chloride (C7H11ClN2O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
