Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-2-(2-(5-nitrofuran-2-yl)vinyl)benzofuran.
CATO supplies 5-Chloro-2-(2-(5-nitrofuran-2-yl)vinyl)benzofuran (CAS 89266-55-7), a certified reference material (molecular formula C14H8ClNO4, MW 289.67 g/mol) for analytical method development and quality control.
5-Chloro-2-(2-(5-nitrofuran-2-yl)vinyl)benzofuran (C14H8ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), 5-Chloro-2-(2-(5-nitrofuran-2-yl)vinyl)benzofuran 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.
