Chemical Structure
Description
As a certified reference material (CRM), Prazosin-d8 (hydrochloride) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Prazosin-d8 (hydrochloride) (CAS 1189508-34-6), molecular formula C19H13D8N5O4HCl and molecular weight 427.91 g/mol, is a CATO reference standard with documented purity and traceability.
Prazosin-d8 (hydrochloride) (C19H13D8N5O4HCl) contains deuterium isotope labeling, a flavonoid core, 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.
