Description
5-Chloro-2-mercaptobenzimidazole is a heterocyclic organosulfur compound with CAS number 25369-78-2, empirical formula C₇H₅ClN₂S and molar mass 184,65 g/mol. Its benzimidazole core bears a chlorine substituent at the 5-position and a mercapto group at the 2-position, providing distinctive reactivity for further functionalisation in organic synthesis. UN number 2811 applies, so handling should follow procedures appropriate for toxic organic solids. Researchers engaged in medicinal chemistry, coordination chemistry or structure–activity exploration can incorporate this substituted mercaptobenzimidazole into multi-step sequences and exploratory routes. Clear molecular identity and practical pack size support reproducible experimental design and inventory control. The product sits within the biochemicals range and is intended for professional use in controlled laboratory environments where well-characterised building blocks are required.

Questions about 5-Chloro-2-mercaptobenzimidazole, 25 g
What is this article?
5-Chloro-2-mercaptobenzimidazole, 25 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.
