Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 4-carbamoyl-1,2-dimethyl-5-oxo-4,5-dihydro-1H-pyrrole-3-carboxylate (CAS 31926-75-7), molecular formula C10H14N2O4 and molecular weight 226.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 4-carbamoyl-1,2-dimethyl-5-oxo-4,5-dihydro-1H-pyrrole-3-carboxylate (C10H14N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 226.23 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
