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 0158AF 5-Bromo-2-chloro-4-(tributylstannyl)pyridine 821773-99-3 C17H29BrClNSn (CAS 821773-99-3), a certified reference material (molecular formula C17H29BrClNSn, MW 481.49 g/mol) for analytical method development and quality control.
0158AF 5-Bromo-2-chloro-4-(tributylstannyl)pyridine 821773-99-3 C17H29BrClNSn (C17H29BrClNSn) contains a nitrile group, chlorine/bromine 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), 0158AF 5-Bromo-2-chloro-4-(tributylstannyl)pyridine 821773-99-3 C17H29BrClNSn 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.
