Chemical Structure
Description
As a certified reference material (CRM), 5-(2,3,4,5,6-Pentafluorophenyl)-2-thiophene carbaldehyde 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.
5-(2,3,4,5,6-Pentafluorophenyl)-2-thiophene carbaldehyde (CAS 893738-03-9) is a high-purity analytical reference standard with the molecular formula C11H3F5OS and a molecular weight of 278.20 g/mol.
5-(2,3,4,5,6-Pentafluorophenyl)-2-thiophene carbaldehyde (C11H3F5OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
