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 7-Amino-4-methyl-3-coumarinacetic acid N-succinimidyl ester, 90%.
7-Amino-4-methyl-3-coumarinacetic acid N-succinimidyl ester, 90% (CAS 113721-87-2) is a high-purity analytical reference standard with the molecular formula C16H14N2O6 and a molecular weight of 330.29 g/mol.
7-Amino-4-methyl-3-coumarinacetic acid N-succinimidyl ester, 90% (C16H14N2O6) 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 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), 7-Amino-4-methyl-3-coumarinacetic acid N-succinimidyl ester, 90% 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.
