Chemical Structure
Description
Structurally, 2-Methyl-2,3-butadienoic acid ethyl ester 5717-41-9 Ethyl 1-methylallene-1-carboxylate Ethyl 2,3-butadiene-2-carboxylate Ethyl 2-methyl-2,3-butadienoate (C7H10O2) contains a carboxylic acid 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 126.15 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).
2-Methyl-2,3-butadienoic acid ethyl ester 5717-41-9 Ethyl 1-methylallene-1-carboxylate Ethyl 2,3-butadiene-2-carboxylate Ethyl 2-methyl-2,3-butadienoate (CAS 5717-41-9) is a high-purity analytical reference standard with the molecular formula C7H10O2 and a molecular weight of 126.15 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
