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 4-[(2-Ethoxy-2-oxoethyl)amino]-4-oxobutanoic acid.
4-[(2-Ethoxy-2-oxoethyl)amino]-4-oxobutanoic acid (CAS 69622-18-0), molecular formula C8H13NO5 and molecular weight 203.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-[(2-Ethoxy-2-oxoethyl)amino]-4-oxobutanoic acid (C8H13NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 203.19 g/mol, it falls into the medium-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.
As a certified reference material (CRM), 4-[(2-Ethoxy-2-oxoethyl)amino]-4-oxobutanoic acid 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.
