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 Seraspenide；Ac-Ser-Asp-Lys-Pro.
CATO supplies Seraspenide；Ac-Ser-Asp-Lys-Pro (CAS 127103-11-1), a certified reference material (molecular formula C20H33N5O9, MW 487.50 g/mol) for analytical method development and quality control.
Seraspenide；Ac-Ser-Asp-Lys-Pro (C20H33N5O9) contains a flavonoid core, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Seraspenide；Ac-Ser-Asp-Lys-Pro 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.
