Chemical Structure
Description
The occurrence of 5-(2-aminoethyl)-4-(propan-2-yl)-4H-1,2,4-triazole-3-thiol hydrochloride is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(2-aminoethyl)-4-(propan-2-yl)-4H-1,2,4-triazole-3-thiol hydrochloride (CAS 1258652-25-3), molecular formula C7H14N4SHCl and molecular weight 222.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(2-aminoethyl)-4-(propan-2-yl)-4H-1,2,4-triazole-3-thiol hydrochloride (C7H14N4SHCl) 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.
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), 5-(2-aminoethyl)-4-(propan-2-yl)-4H-1,2,4-triazole-3-thiol 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.
