Chemical Structure
Description
The occurrence of (1H-1,2,3-Triazol-5-yl)methanol hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (1H-1,2,3-Triazol-5-yl)methanol hydrochloride (CAS 1803599-12-3), a certified reference material (molecular formula C3H5N3OHCl, MW 135.55 g/mol) for analytical method development and quality control.
The molecular framework of (1H-1,2,3-Triazol-5-yl)methanol hydrochloride (C3H5N3OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
