Chemical Structure
Description
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.
1H-1,2,4-Triazole-5-carbaldehyde hydrochloride (CAS 853806-15-2) is a high-purity analytical reference standard with the molecular formula C3H3N3OHCl and a molecular weight of 133.53 g/mol.
Based on its molecular formula C3H3N3OHCl, 1H-1,2,4-Triazole-5-carbaldehyde hydrochloride contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 133.53 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
