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.
Diethyl 5-((2-ethoxy-2-oxoethyl)thio)-3-methylthiophene-2,4-dicarboxylate (CAS 860786-08-9) is a high-purity analytical reference standard with the molecular formula C15H20O6S2 and a molecular weight of 360.45 g/mol.
The molecular framework of Diethyl 5-((2-ethoxy-2-oxoethyl)thio)-3-methylthiophene-2,4-dicarboxylate (C15H20O6S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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.
