Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 6-Iodothieno[3,2-d]pyrimidine (CAS 853681-15-9), a certified reference material (molecular formula C6H3IN2S, MW 262.07 g/mol) for analytical method development and quality control.
The molecular framework of 6-Iodothieno[3,2-d]pyrimidine (C6H3IN2S) is characterized by a nitrile group, sulfur-containing functionality, iodine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
