Chemical Structure
Description
The occurrence of 3-(thiophen-3-ylmethyl)-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(thiophen-3-ylmethyl)-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine hydrochloride (CAS 1803610-10-7) is a high-purity analytical reference standard with the molecular formula C10H12N4SHCl and a molecular weight of 256.75 g/mol.
3-(thiophen-3-ylmethyl)-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]pyrazine hydrochloride (C10H12N4SHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3-(thiophen-3-ylmethyl)-5H,6H,7H,8H-[1,2,4]triazolo[4,3-a]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.
