6-Bromo-2-methylpyrazolo[1,5-a]pyrimidine-3-sulfonyl chloride CAS 1306606-65-4 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 6-Bromo-2-methylpyrazolo[1,5-a]pyrimidine-3-sulfonyl chloride.

CATO supplies 6-Bromo-2-methylpyrazolo[1,5-a]pyrimidine-3-sulfonyl chloride (CAS 1306606-65-4), a certified reference material (molecular formula C7H5BrClN3O2S, MW 310.56 g/mol) for analytical method development and quality control.

6-Bromo-2-methylpyrazolo[1,5-a]pyrimidine-3-sulfonyl chloride (C7H5BrClN3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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 6-Bromo-2-methylpyrazolo[1,5-a]pyrimidine-3-sulfonyl chloride 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.
