Chemical Structure
Description
(E)-4-Hydroxycrotonoic Acid Ethyl Ester (CAS 10080-68-9) is a high-purity analytical reference standard with the molecular formula C6H10O3 and a molecular weight of 130.14 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (E)-4-Hydroxycrotonoic Acid Ethyl Ester is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
