Chemical Structure
Description
The occurrence of 2'-(2-Chloroanilino)-6'-(dibutylamino)fluoran is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2'-(2-Chloroanilino)-6'-(dibutylamino)fluoran (CAS 82137-81-3) is a high-purity analytical reference standard with the molecular formula C34H33ClN2O3 and a molecular weight of 553.09 g/mol.
The molecular framework of 2'-(2-Chloroanilino)-6'-(dibutylamino)fluoran (C34H33ClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
