Chemical Structure

3-Methyl-1-vinyl-1H-pyrazole-4-carbaldehyde CAS 120841-95-4 chemical structure

Description

CATO supplies 3-Methyl-1-vinyl-1H-pyrazole-4-carbaldehyde (CAS 120841-95-4), a certified reference material (molecular formula C7H8N2O, MW 136.15 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-Methyl-1-vinyl-1H-pyrazole-4-carbaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.15 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 3-Methyl-1-vinyl-1H-pyrazole-4-carbaldehyde 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.
