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.

3-Chloro-2-mercapto-5-(trifluoromethyl)pyridine 3-Chloro-2-sulphanyl-5-(trifluoromethyl)pyridine 3-chloro-5-(trifluoromethyl)pyridine-2-thiol 76041-74-2 (CAS 76041-74-2) is a high-purity analytical reference standard with the molecular formula C6H3ClF3NS and a molecular weight of 213.61 g/mol.

Structurally, 3-Chloro-2-mercapto-5-(trifluoromethyl)pyridine 3-Chloro-2-sulphanyl-5-(trifluoromethyl)pyridine 3-chloro-5-(trifluoromethyl)pyridine-2-thiol 76041-74-2 (C6H3ClF3NS) contains a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 213.61 g/mol, it falls into the medium-molecular-weight range. 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).

As a certified reference material (CRM), 3-Chloro-2-mercapto-5-(trifluoromethyl)pyridine 3-Chloro-2-sulphanyl-5-(trifluoromethyl)pyridine 3-chloro-5-(trifluoromethyl)pyridine-2-thiol 76041-74-2 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.
