Chemical Structure
Description
14300-64-2 4299AD C8H10O2S Ethyl 3-methylthiophene-2-carboxylate (CAS 14300-64-2), molecular formula C8H10O2S and molecular weight 170.23 g/mol, is a CATO reference standard with documented purity and traceability.
14300-64-2 4299AD C8H10O2S Ethyl 3-methylthiophene-2-carboxylate (C8H10O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 14300-64-2 4299AD C8H10O2S Ethyl 3-methylthiophene-2-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.
