7-chloro-2-sulfanyl-3,4-dihydroquinazolin-4-one CAS 33017-86-6

Description

Compared with other compounds in its class, the molecular weight of 220.72 g/mol gives 7-chloro-2-sulfanyl-3,4-dihydroquinazolin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-chloro-2-sulfanyl-3,4-dihydroquinazolin-4-one (CAS 33017-86-6), molecular formula C8H13ClN2OS and molecular weight 220.72 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-chloro-2-sulfanyl-3,4-dihydroquinazolin-4-one (C8H13ClN2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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.

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.
