Description
As a certified reference material (CRM), 2-(2-Thienylmethyl)propanedioic Acid 1-Ethyl Ester 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 2-(2-Thienylmethyl)propanedioic Acid 1-Ethyl Ester (CAS 143468-96-6), a certified reference material (molecular formula C10H12O4S, MW 228.26 g/mol) for analytical method development and quality control.
Structurally, 2-(2-Thienylmethyl)propanedioic Acid 1-Ethyl Ester (C10H12O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 228.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
