Description
2-Amino-3-methoxybenzoic acid methyl ester is an ortho-amino benzoate ester used as a building block in organic and medicinal chemistry. It is identified by CAS number 5121-34-6, with the empirical formula C₉H₁₁NO₃ and a molar mass of 181,19 g/mol. The combination of an aromatic amino group, a methoxy substituent, and a methyl ester enables further functionalisation through acylation, cyclisation, or ester transformation routes. A boiling point of 117 °C is reported for the material. The defined formula and mass simplify reaction planning and analytical confirmation. Typical applications include exploratory route scouting, intermediate preparation, and structure–activity studies where a substituted anthranilate motif is required. The convenient pack size is well matched to screening, optimisation, and small preparative batches in research environments.
This article is part of Acids, in Acids & bases.

Questions about 2-Amino-3-methoxybenzoic acid methyl est, er, 2 g
What is this article?
2-Amino-3-methoxybenzoic acid methyl est, er, 2 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
