Chemical Structure
Description
As a certified reference material (CRM), 4-[(4-Chlorophenyl)sulfanyl]-5H-pyrimido[5,4-b]indole 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.
CATO supplies 4-[(4-Chlorophenyl)sulfanyl]-5H-pyrimido[5,4-b]indole (CAS 320420-19-7), a certified reference material (molecular formula C16H10ClN3S, MW 311.79 g/mol) for analytical method development and quality control.
4-[(4-Chlorophenyl)sulfanyl]-5H-pyrimido[5,4-b]indole (C16H10ClN3S) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
