1286AF 4-Chloro-6-(tributylstannyl)-thieno[3,2-d]pyrimidine 875339-90-5 C18H29ClN2SSn (CAS 875339-90-5), molecular formula C18H37ClN2SSn and molecular weight 467.73 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H37ClN2SSn, 1286AF 4-Chloro-6-(tributylstannyl)-thieno[3,2-d]pyrimidine 875339-90-5 C18H29ClN2SSn contains sulfur-containing functionality, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 467.73 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
