Chemical Structure
Description
As a certified reference material (CRM), 1-(5-ethyl-1H-1,2,4-triazol-3-yl)ethan-1-ol 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.
1-(5-ethyl-1H-1,2,4-triazol-3-yl)ethan-1-ol hydrochloride (CAS 1955548-47-6), molecular formula C6H11N3OHCl and molecular weight 177.63 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H11N3OHCl, 1-(5-ethyl-1H-1,2,4-triazol-3-yl)ethan-1-ol hydrochloride contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 177.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
