Chemical Structure

Ethyltri-n-propyltin CAS 3440-79-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 277.03 g/mol gives Ethyltri-n-propyltin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyltri-n-propyltin (CAS 3440-79-7) is a high-purity analytical reference standard with the molecular formula C11H26Sn and a molecular weight of 277.03 g/mol.

Structurally, Ethyltri-n-propyltin (C11H26Sn) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 277.03 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures Ethyltri-n-propyltin 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.
