Description

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

851973-08-5 1,5-Dimethyl-1H-pyrazole-4-carbonyl chloride DTXSID90390245 (CAS 851973-08-5) is a high-purity analytical reference standard with the molecular formula C6H7ClN2O and a molecular weight of 158.59 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 851973-08-5 1,5-Dimethyl-1H-pyrazole-4-carbonyl chloride DTXSID90390245 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.59 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 851973-08-5 1,5-Dimethyl-1H-pyrazole-4-carbonyl chloride DTXSID90390245 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.
