Chemical Structure
Description
The molecular framework of 7-Nitro-1,3-dioxaindane-5-carboxylic acid (C8H5NO6) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
7-Nitro-1,3-dioxaindane-5-carboxylic acid (CAS 7112-72-3), molecular formula C8H5NO6 and molecular weight 211.13 g/mol, is a CATO reference standard with documented purity and traceability.
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.
