Chemical Structure
Description
The occurrence of Methyl 3-amino-2,6-dichlorobenzoate 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.
Methyl 3-amino-2,6-dichlorobenzoate (CAS 1340366-65-5), molecular formula C8H7Cl2NO2 and molecular weight 220.05 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H7Cl2NO2, Methyl 3-amino-2,6-dichlorobenzoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
