Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl (E)-4-hydroxy-3-methylbut-2-enoate.
Ethyl (E)-4-hydroxy-3-methylbut-2-enoate (CAS 65527-85-7), molecular formula C7H12O3 and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl (E)-4-hydroxy-3-methylbut-2-enoate (C7H12O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
