Chemical Structure
Description
N-((1-Cyclopentyl-5-(pyridin-4-yl)-1H-pyrazol-3-yl)methyl)benzo[c][1,2,5]thiadiazole-5-carboxamide (CAS 1421501-45-2) is a high-purity analytical reference standard with the molecular formula C21H20N6OS and a molecular weight of 404.49 g/mol.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, N-((1-Cyclopentyl-5-(pyridin-4-yl)-1H-pyrazol-3-yl)methyl)benzo[c][1,2,5]thiadiazole-5-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
