Chemical Structure

4,6-dichloro-5-nitronicotinic acid CAS 1192263-83-4 chemical structure

Description

The occurrence of 4,6-dichloro-5-nitronicotinic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,6-dichloro-5-nitronicotinic acid (CAS 1192263-83-4), a certified reference material (molecular formula C6H2Cl2N2O4, MW 237.00 g/mol) for analytical method development and quality control.

Structurally, 4,6-dichloro-5-nitronicotinic acid (C6H2Cl2N2O4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 237.00 g/mol, it falls into the medium-molecular-weight range. 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.
