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 Ethyl 7-methyl-2-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidine-6-carboxylate.
Ethyl 7-methyl-2-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidine-6-carboxylate (CAS 162286-69-3), molecular formula C14H13N3O2S and molecular weight 287.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 7-methyl-2-(thiophen-2-yl)pyrazolo[1,5-a]pyrimidine-6-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.34 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.
