Chemical Structure

2-Chloroethyl Isothiocyanate CAS 6099-88-3 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.

CATO supplies 2-Chloroethyl Isothiocyanate (CAS 6099-88-3), a certified reference material (molecular formula C3H4ClNS, MW 121.59 g/mol) for analytical method development and quality control.

The molecular framework of 2-Chloroethyl Isothiocyanate (C3H4ClNS) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
