Chemical Structure
Description
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.
5,6,7,8-Tetrahydro-[1,2,4]triazolo[4,3-a]pyridine hydrochloride (CAS 1211450-17-7) is a high-purity analytical reference standard with the molecular formula C5H8N4HCl and a molecular weight of 160.60 g/mol.
Owing to a nitrile group, chlorine substitution, 5,6,7,8-Tetrahydro-[1,2,4]triazolo[4,3-a]pyridine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
