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 2-Butyl-4-chloro-6,7-dihydro-5h-cyclopenta[4,5]thieno[2,3-d]pyrimidine (CAS 1501372-11-7), a certified reference material (molecular formula C13H15ClN2S, MW 266.79 g/mol) for analytical method development and quality control.
2-Butyl-4-chloro-6,7-dihydro-5h-cyclopenta[4,5]thieno[2,3-d]pyrimidine (C13H15ClN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-Butyl-4-chloro-6,7-dihydro-5h-cyclopenta[4,5]thieno[2,3-d]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
