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 2-(Chloromethyl)thieno[3,2-d]pyrimidin-4(3H)-one.
CATO supplies 2-(Chloromethyl)thieno[3,2-d]pyrimidin-4(3H)-one (CAS 147005-91-2), a certified reference material (molecular formula C7H5ClN2OS, MW 200.65 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H5ClN2OS, 2-(Chloromethyl)thieno[3,2-d]pyrimidin-4(3H)-one contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
