Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 207.01 g/mol gives 2,6-Dichloro-3-nitroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,6-Dichloro-3-nitroaniline (CAS 13785-48-3), a certified reference material (molecular formula C6H4Cl2N2O2, MW 207.01 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,6-Dichloro-3-nitroaniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
