Structurally, 2949-22-6 Acetic acid, isocyanato-, ethyl ester Ethyl isocyanatoacetate Acetic acid, 2-isocyanato-, ethyl ester AI3-52377 Carbethoxymethyl isocyanate EINECS 220-967-4 Ethoxycarbonylmethyl isocyanate Ethyl glycolate isocyanate Isocyanatoacetic acid ethyl ester Isocyanatoethyl acetate NSC 56429 NSC 6276 (C5H7NO3) 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 129.11 g/mol, it falls into the low-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.
