Chemical Structure
Description
As a certified reference material (CRM), Ac-muramyl-Ala-Glu-NH? 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.
CATO supplies Ac-muramyl-Ala-Glu-NH? (CAS 59331-38-3), a certified reference material (molecular formula C19H32N4O11, MW 492.48 g/mol) for analytical method development and quality control.
Structurally, Ac-muramyl-Ala-Glu-NH? (C19H32N4O11) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 492.48 g/mol, it falls into the moderately-high-molecular-weight range. 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.
