Chemical Structure

Methyl 5-(tert-butyl)thiophene-2-carboxylate CAS 229003-19-4 chemical structure

Description

As a certified reference material (CRM), Methyl 5-(tert-butyl)thiophene-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.

Methyl 5-(tert-butyl)thiophene-2-carboxylate (CAS 229003-19-4) is a high-purity analytical reference standard with the molecular formula C10H14O2S and a molecular weight of 198.28 g/mol.

Methyl 5-(tert-butyl)thiophene-2-carboxylate (C10H14O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
