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 2-(Furan-2-yl)-4-nitrobenzoic acid.
2-(Furan-2-yl)-4-nitrobenzoic acid (CAS 1261908-82-0) is a high-purity analytical reference standard with the molecular formula C11H7NO5 and a molecular weight of 233.18 g/mol.
The molecular framework of 2-(Furan-2-yl)-4-nitrobenzoic acid (C11H7NO5) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
