Chemical Structure

3-Methoxy-1-methyl-1H-pyrazole-4-carbonyl chloride CAS 332070-70-9 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 3-Methoxy-1-methyl-1H-pyrazole-4-carbonyl chloride.

CATO supplies 3-Methoxy-1-methyl-1H-pyrazole-4-carbonyl chloride (CAS 332070-70-9), a certified reference material (molecular formula C6H7ClN2O2, MW 174.58 g/mol) for analytical method development and quality control.

Structurally, 3-Methoxy-1-methyl-1H-pyrazole-4-carbonyl chloride (C6H7ClN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 174.58 g/mol, it falls into the medium-molecular-weight range. 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 3-Methoxy-1-methyl-1H-pyrazole-4-carbonyl 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.
