The occurrence of 7-(3,4-Dichlorophenyl)-2-(4-(pyridin-2-yl)piperazin-1-yl)thieno[3,2-d]pyrimidin-4-ol is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-(3,4-Dichlorophenyl)-2-(4-(pyridin-2-yl)piperazin-1-yl)thieno[3,2-d]pyrimidin-4-ol (CAS 1251699-11-2), a certified reference material (molecular formula C21H17Cl2N5OS, MW 458.36 g/mol) for analytical method development and quality control.
7-(3,4-Dichlorophenyl)-2-(4-(pyridin-2-yl)piperazin-1-yl)thieno[3,2-d]pyrimidin-4-ol (C21H17Cl2N5OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
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.
