Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
2-(Chloromethyl)-6-methyl-5-(2-methylbutyl)thieno[2,3-d]pyrimidin-4(3h)-one (CAS 742094-59-3), molecular formula C13H17ClN2OS and molecular weight 284.80 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Chloromethyl)-6-methyl-5-(2-methylbutyl)thieno[2,3-d]pyrimidin-4(3h)-one (C13H17ClN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
