Description
As a certified reference material (CRM), 5-(5-Methylthiophen-2-yl)thiophene-2-carboxylic acid 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.
CATO supplies 5-(5-Methylthiophen-2-yl)thiophene-2-carboxylic acid (CAS 30979-83-0), a certified reference material (molecular formula C10H8O2S2, MW 224.30 g/mol) for analytical method development and quality control.
5-(5-Methylthiophen-2-yl)thiophene-2-carboxylic acid (C10H8O2S2) 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.
