Chemical Structure

Tri-p-tolylhydroxytin CAS 38049-84-2 chemical structure

Description

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.

Tri-p-tolylhydroxytin (CAS 38049-84-2), molecular formula C21H22OSn and molecular weight 409.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, Tri-p-tolylhydroxytin is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 409.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
