Chemical Structure
Description
As a certified reference material (CRM), n-Cyclopentyl-4-fluorobenzo[b]thiophene-2-carboxamide 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.
n-Cyclopentyl-4-fluorobenzo[b]thiophene-2-carboxamide (CAS 923726-95-8), molecular formula C14H14FNOS and molecular weight 263.33 g/mol, is a CATO reference standard with documented purity and traceability.
n-Cyclopentyl-4-fluorobenzo[b]thiophene-2-carboxamide (C14H14FNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. 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 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.
