Chemical Structure

(S)-2-Chloro-7-methyl-7,8-dihydropteridin-6(5H)-one CAS 2379584-01-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 198.61 g/mol gives (S)-2-Chloro-7-methyl-7,8-dihydropteridin-6(5H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-2-Chloro-7-methyl-7,8-dihydropteridin-6(5H)-one (CAS 2379584-01-5), molecular formula C7H7ClN4O and molecular weight 198.61 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-2-Chloro-7-methyl-7,8-dihydropteridin-6(5H)-one (C7H7ClN4O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine 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.

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.
