Chemical Structure
Description
Tributyl(5-fluoro-2-methylphenyl)stannane (CAS 223432-25-5), molecular formula C19H33FSn and molecular weight 399.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tributyl(5-fluoro-2-methylphenyl)stannane (C19H33FSn) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Tributyl(5-fluoro-2-methylphenyl)stannane 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.
