Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-((1-(4-(Tert-butyl)phenyl)-4-cyano-6,7-dihydro-5H-cyclopenta[c]pyridin-3-yl)thio)acetamide (CAS 861209-37-2) is a high-purity analytical reference standard with the molecular formula C21H23N3OS and a molecular weight of 365.49 g/mol.
2-((1-(4-(Tert-butyl)phenyl)-4-cyano-6,7-dihydro-5H-cyclopenta[c]pyridin-3-yl)thio)acetamide (C21H23N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
