Description
Benzo[b]thiophene-2-carboxylic acid is a heterocyclic carboxylic acid offered at a minimum purity of 95 %, identified by CAS number 6314-28-9 and empirical formula C₉H₆O₂S. The molar mass is 178,21 g/mol and the boiling point is 280,4 °C. The fused aromatic system supports coupling, amidation, and further ring functionalisation in research programmes. Material from manufacturer Carl ROTH provides a defined min. 95 % grade suitable for method development, intermediate preparation, and small-scale library work. Laboratories select this building block when a sulphur-containing bicyclic acid is required with transparent molar-mass and boiling-point data. Use under standard organic-laboratory conditions appropriate for carboxylic acids of this type.
This article is part of Acids, in Acids & bases.

Questions about Benzo[b]thiophene-2-carboxylic acid, min. 95 %, 2 g
What is this article?
Benzo[b]thiophene-2-carboxylic acid, min. 95 %, 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.
