Chemical Structure

2,5-Dithiocyanatothiophene CAS 34099-59-7 chemical structure

Description

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.

2,5-Dithiocyanatothiophene (CAS 34099-59-7), molecular formula C6H2N2S3 and molecular weight 198.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,5-Dithiocyanatothiophene (C6H2N2S3) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. 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).

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.
