4-(chloromethyl)-1-(2-methanesulfonylethyl)-3,5-dimethyl-1H-pyrazole hydrochloride CAS 1803583-05-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(chloromethyl)-1-(2-methanesulfonylethyl)-3,5-dimethyl-1H-pyrazole hydrochloride.

CATO supplies 4-(chloromethyl)-1-(2-methanesulfonylethyl)-3,5-dimethyl-1H-pyrazole hydrochloride (CAS 1803583-05-2), a certified reference material (molecular formula C9H15ClN2O2SHCl, MW 287.20 g/mol) for analytical method development and quality control.

4-(chloromethyl)-1-(2-methanesulfonylethyl)-3,5-dimethyl-1H-pyrazole hydrochloride (C9H15ClN2O2SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

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

CATO manufactures 4-(chloromethyl)-1-(2-methanesulfonylethyl)-3,5-dimethyl-1H-pyrazole hydrochloride 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.
