Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ethyl N-{[1-(2-hydroxyethyl)-2,4-dioxo-1,2,3,4-tetrahydro-5-pyrimidinyl]carbonyl}carbamate (CAS 303997-18-4), a certified reference material (molecular formula C10H13N3O6, MW 271.23 g/mol) for analytical method development and quality control.
Structurally, Ethyl N-{[1-(2-hydroxyethyl)-2,4-dioxo-1,2,3,4-tetrahydro-5-pyrimidinyl]carbonyl}carbamate (C10H13N3O6) contains an amino-acid-derived structure, 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 271.23 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.
