Chemical Structure

1-(Sec-butyl)-4-ethynyl-1H-pyrazole CAS 2098029-52-6 chemical structure

Description

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

1-(Sec-butyl)-4-ethynyl-1H-pyrazole (CAS 2098029-52-6), molecular formula C9H12N2 and molecular weight 148.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-(Sec-butyl)-4-ethynyl-1H-pyrazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.20 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).

CATO manufactures 1-(Sec-butyl)-4-ethynyl-1H-pyrazole 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.
