Description
o-Toluic acid is an aromatic carboxylic acid offered at 98 % purity for synthesis, identified by CAS number 118-90-1 and empirical formula C₈H₈O₂. With a molar mass of 136,15 g/mol and a density of 1,062 g/cm³, the solid shows a flash point of 148 °C and a boiling range of 258 to 259 °C, supporting controlled handling in organic laboratory workflows. This synthesis grade is suited to building-block chemistry, esterification and related transformations where an ortho-substituted benzoic acid derivative is required as a defined intermediate. The product is EG number 202-803-3 places the substance within the European inventory framework. Laboratories use o-toluic acid in the preparation of specialty intermediates, fine-chemical routes and structure–activity studies that rely on the ortho-methyl aromatic acid motif. Standard organic-acid precautions apply during weighing, dissolution and reaction setup to maintain reproducibility and safe practice across synthetic campaigns.

Questions about o-Toluic acid, 98 %, for synthesis, 250 g, plastic
What is this article?
o-Toluic acid, 98 %, for synthesis, 250 g, plastic 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.
