Description

Compared with other compounds in its class, the molecular weight of 224.65 g/mol gives 2,5-Difluorobenzothiohydrazide hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,5-Difluorobenzothiohydrazide hydrochloride (CAS 1018690-17-9), molecular formula C7H6F2N2SHCl and molecular weight 224.65 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,5-Difluorobenzothiohydrazide hydrochloride (C7H6F2N2SHCl) 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 224.65 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).

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.

As a certified reference material (CRM), 2,5-Difluorobenzothiohydrazide hydrochloride 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.
