Chemical Structure
Description
The occurrence of 2-Hydrazinyl-3-((trifluoromethyl)thio)pyrazine hydrochloride is closely related to a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Hydrazinyl-3-((trifluoromethyl)thio)pyrazine hydrochloride (CAS 1286744-02-2), molecular formula C5H5F3N4SHCl and molecular weight 246.63 g/mol, is a CATO reference standard with documented purity and traceability.
2-Hydrazinyl-3-((trifluoromethyl)thio)pyrazine hydrochloride (C5H5F3N4SHCl) contains a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-Hydrazinyl-3-((trifluoromethyl)thio)pyrazine 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.
