(S)-6-(3-Methyl-1H-pyrazol-4-yl)-2-(quinuclidin-2-yl)thieno[3,2-d]pyrimidin-4(1H)-one CAS 1330782-76-7 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 (S)-6-(3-Methyl-1H-pyrazol-4-yl)-2-(quinuclidin-2-yl)thieno[3,2-d]pyrimidin-4(1H)-one.

(S)-6-(3-Methyl-1H-pyrazol-4-yl)-2-(quinuclidin-2-yl)thieno[3,2-d]pyrimidin-4(1H)-one (CAS 1330782-76-7) is a high-purity analytical reference standard with the molecular formula C17H19N5OS and a molecular weight of 341.43 g/mol.

The molecular framework of (S)-6-(3-Methyl-1H-pyrazol-4-yl)-2-(quinuclidin-2-yl)thieno[3,2-d]pyrimidin-4(1H)-one (C17H19N5OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
