Chemical Structure
Description
The occurrence of 2-(allyloxy)ethyl 3-oxobutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(allyloxy)ethyl 3-oxobutanoate (CAS 77757-00-7) is a high-purity analytical reference standard with the molecular formula C9H14O4 and a molecular weight of 186.21 g/mol.
The molecular framework of 2-(allyloxy)ethyl 3-oxobutanoate (C9H14O4) 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. 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.
As a certified reference material (CRM), 2-(allyloxy)ethyl 3-oxobutanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
