Chemical Structure

4-Phenyl-1,3-thiazolidine-2-thione CAS 1908-90-3 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.

4-Phenyl-1,3-thiazolidine-2-thione (CAS 1908-90-3), molecular formula C9H9NS2 and molecular weight 195.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Phenyl-1,3-thiazolidine-2-thione (C9H9NS2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
