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 19775-48-5 C32H49NO4 Daphmacrine W1193.
19775-48-5 C32H49NO4 Daphmacrine W1193 (CAS 19775-48-5), molecular formula C32H49NO4 and molecular weight 511.74 g/mol, is a CATO reference standard with documented purity and traceability.
19775-48-5 C32H49NO4 Daphmacrine W1193 (C32H49NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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), 19775-48-5 C32H49NO4 Daphmacrine W1193 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.
