Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
[3-(Pyridin-4-yl)-1,2,4-oxadiazol-5-yl]methanamine dihydrochloride (CAS 1181458-05-8), molecular formula C8H8N4OHCl and molecular weight 212.64 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, [3-(Pyridin-4-yl)-1,2,4-oxadiazol-5-yl]methanamine dihydrochloride (C8H8N4OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 212.64 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
