Description
2,5-Dimercapto-1,3,4-thiadiazole is a sulfur-rich heterocyclic reagent for chemical and biochemical laboratory use. It is registered under CAS number 1072-71-5 with the empirical formula C₂H₂N₂S₃ and a molar mass of 150,25 g/mol. The material has a flash point of 111 °C and is associated with UN number 3077, supporting consistent classification and transport documentation in regulated laboratory settings. The dual thiol functionality on the 1,3,4-thiadiazole ring makes the compound relevant for coordination chemistry, cross-linking concepts and the construction of sulfur-containing building blocks. Product data from manufacturer Carl ROTH provide the identity and physical anchors required for SOPs, risk assessments and batch records. Research and development groups can deploy the reagent in method scouting, scale-up exercises and specialty chemical programmes that demand a defined heterocyclic dithiol. Clear CAS, formula and molar-mass information streamline receiving, labelling and inventory management across multi-user laboratories.

Questions about 2,5-Dimercapto-1,3,4-thiadiazole, 500 g
What is this article?
2,5-Dimercapto-1,3,4-thiadiazole, 500 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
