Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 438.02 g/mol gives 3,5-Dichloro-2-(tributylstannyl)pyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,5-Dichloro-2-(tributylstannyl)pyrazine (CAS 446285-70-7), a certified reference material (molecular formula C16H28Cl2N2Sn, MW 438.02 g/mol) for analytical method development and quality control.
3,5-Dichloro-2-(tributylstannyl)pyrazine (C16H28Cl2N2Sn) contains a nitrile group, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3,5-Dichloro-2-(tributylstannyl)pyrazine 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.
