Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 511.64 g/mol gives Etamiphylline Camsylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Etamiphylline Camsylate (CAS 19326-29-5), molecular formula C13H21N5O2C10H16O4S and molecular weight 511.64 g/mol, is a CATO reference standard with documented purity and traceability.
Etamiphylline Camsylate (C13H21N5O2C10H16O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
As a certified reference material (CRM), Etamiphylline Camsylate 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.
