Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 5-(2-aminoethyl)-1,2,4-oxadiazole-3-carboxylate hydrochloride.
CATO supplies Ethyl 5-(2-aminoethyl)-1,2,4-oxadiazole-3-carboxylate hydrochloride (CAS 890713-72-1), a certified reference material (molecular formula C7H11N3O3HCl, MW 221.64 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 5-(2-aminoethyl)-1,2,4-oxadiazole-3-carboxylate hydrochloride (C7H11N3O3HCl) is characterized by an amide group, a carboxylic acid 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
