6-(3,5-Dimethyl-1H-pyrazol-1-yl)-3-(4-methoxyphenyl)-7-(3-nitrophenyl)pyrazolo[1,5-a]pyrimidine CAS 956755-29-6

Description

The occurrence of 6-(3,5-Dimethyl-1H-pyrazol-1-yl)-3-(4-methoxyphenyl)-7-(3-nitrophenyl)pyrazolo[1,5-a]pyrimidine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-(3,5-Dimethyl-1H-pyrazol-1-yl)-3-(4-methoxyphenyl)-7-(3-nitrophenyl)pyrazolo[1,5-a]pyrimidine (CAS 956755-29-6) is a high-purity analytical reference standard with the molecular formula C24H20N6O3 and a molecular weight of 440.45 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 6-(3,5-Dimethyl-1H-pyrazol-1-yl)-3-(4-methoxyphenyl)-7-(3-nitrophenyl)pyrazolo[1,5-a]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 440.45 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
