Chemical Structure

7-chloro-5-(chloromethyl)-1H-pyrazolo[4,3-d]pyrimidine CAS 2932453-23-9 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 7-chloro-5-(chloromethyl)-1H-pyrazolo[4,3-d]pyrimidine.

CATO supplies 7-chloro-5-(chloromethyl)-1H-pyrazolo[4,3-d]pyrimidine (CAS 2932453-23-9), a certified reference material (molecular formula C6H4Cl2N4, MW 203.03 g/mol) for analytical method development and quality control.

Owing to a nitrile group, chlorine substitution, an aromatic ring system, 7-chloro-5-(chloromethyl)-1H-pyrazolo[4,3-d]pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 7-chloro-5-(chloromethyl)-1H-pyrazolo[4,3-d]pyrimidine 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.
