Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 227.65 g/mol gives Albendazole EP Impurity E Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Albendazole EP Impurity E Hydrochloride (CAS 37574-18-8), a certified reference material (molecular formula C9H9N3O2HCl, MW 227.65 g/mol) for analytical method development and quality control.
Albendazole EP Impurity E Hydrochloride (C9H9N3O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
