Description
CATO manufactures 1,2-Bis(tributylstannyl)ethyne under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1,2-Bis(tributylstannyl)ethyne (CAS 994-71-8) is a high-purity analytical reference standard with the molecular formula C26H54Sn2 and a molecular weight of 604.13 g/mol.
1,2-Bis(tributylstannyl)ethyne (C26H54Sn2) contains an organic framework. 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
