Description

Compared with other compounds in its class, the molecular weight of 256.32 g/mol gives Ethyl 5-(2-acetoxyethyl)-4-methylthiophene-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 5-(2-acetoxyethyl)-4-methylthiophene-3-carboxylate (CAS 19156-47-9), molecular formula C12H16O4S and molecular weight 256.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 5-(2-acetoxyethyl)-4-methylthiophene-3-carboxylate (C12H16O4S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Ethyl 5-(2-acetoxyethyl)-4-methylthiophene-3-carboxylate 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.
