Chemical Structure
Description
The occurrence of 20248-64-0 4,6-dichlorobenzene-1,3-diamine DTXSID30391897 is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
20248-64-0 4,6-dichlorobenzene-1,3-diamine DTXSID30391897 (CAS 20248-64-0) is a high-purity analytical reference standard with the molecular formula C6H6Cl2N2 and a molecular weight of 177.03 g/mol.
The molecular framework of 20248-64-0 4,6-dichlorobenzene-1,3-diamine DTXSID30391897 (C6H6Cl2N2) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. 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.
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.
