Chemical Structure
Description
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.
5-[3,4-(Ethylenedioxy)phenyl]-3-methyl-5-oxovaleric acid (CAS 951894-15-8), molecular formula C14H16O5 and molecular weight 264.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-[3,4-(Ethylenedioxy)phenyl]-3-methyl-5-oxovaleric acid (C14H16O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
