n-Butyltin trichloride CAS 1118-46-3 chemical structure

Description

As a certified reference material (CRM), n-Butyltin trichloride 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.

n-Butyltin trichloride (CAS 1118-46-3), molecular formula C4H9Cl3Sn and molecular weight 282.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of n-Butyltin trichloride (C4H9Cl3Sn) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
