Chemical Structure
Description
The occurrence of 5-Nitrobenzene-1,2,3-triol is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Nitrobenzene-1,2,3-triol (CAS 14416-24-1), molecular formula C6H5NO5 and molecular weight 171.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Nitrobenzene-1,2,3-triol (C6H5NO5) is characterized by a carbohydrate-derived structure, an amide group. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
