Description
CATO supplies 2,5-Bis(tributylstannyl)thiophene (CAS 145483-63-2), a certified reference material (molecular formula C28H60SSn2, MW 666.26 g/mol) for analytical method development and quality control.
Based on its molecular formula C28H60SSn2, 2,5-Bis(tributylstannyl)thiophene contains sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 666.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2,5-Bis(tributylstannyl)thiophene 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.
