Description
5-Methoxy-2-mercaptobenzimidazole is an organic heterocyclic compound with CAS number 37052-78-1 and empirical formula C₈H₈N₂OS. This benzimidazole derivative bears a methoxy substituent and a mercapto group and has a molar mass of 180,23 g/mol. Reported physical data include a flash point of 140,9 °C and a boiling point of 309,4 °C, supporting informed handling and process planning in the laboratory. Mercaptobenzimidazoles are frequently used when constructing nitrogen- and sulfur-containing scaffolds, exploring thiol-based reactivity, or preparing specialty intermediates for further transformation. The defined composition and thermal profile help laboratories maintain reproducible conditions across synthetic routes, method development, and analytical workflows. This product suits chemical and biochemical settings that require a clearly specified heterocyclic building block for academic or industrial experimental programmes involving aromatic heterocycles.

Questions about 5-Methoxy-2-mercaptobenzimidazole, 250 g
What is this article?
5-Methoxy-2-mercaptobenzimidazole, 250 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Bases & alkalis, inside Acids & bases, in Lab chemicals.
A base or an alkali is sodium hydroxide, potassium hydroxide, ammonia and their relatives, as solid or as solution. The carbonate that a hydroxide picks up from the air changes a titre. Concentration and purity are the specification. Concentrated alkalis attack skin and aluminium.
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.
