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 L-Aspartyl-L-lysine.
L-Aspartyl-L-lysine (CAS 5853-83-8) is a high-purity analytical reference standard with the molecular formula C10H19N3O5 and a molecular weight of 261.27 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, L-Aspartyl-L-lysine is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures L-Aspartyl-L-lysine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
