Description
Dimidium bromide is a biochemical reagent supplied at a minimum purity of 95 % for laboratory use in biochemistry and related analytical applications. It carries CAS number 518-67-2 and EG number 208-256-7, with the empirical formula C₂₀H₁₈BrN₃ and a molar mass of 380,30 g/mol. These identifiers support accurate documentation in method sheets, reagent inventories and analytical reports. The compound is packed as 500 mg in glass, a practical quantity for biochemical staining, complexometric or surfactant-related determinations where dimidium bromide is employed as a dye or indicator component. Available from manufacturer Carl ROTH, this grade is oriented toward professional biochemistry workflows, including water-analysis contexts such as surfactant determination. Clear specification of purity, molecular formula and molar mass helps laboratories maintain traceable reagent selection without additional reformulation. The glass presentation protects the solid during storage and weighing. Dimidium bromide min. 95 % thus provides a defined, application-ready material for routine and specialised biochemical procedures that require this phenanthridinium bromide salt.

Questions about Dimidium bromide, min. 95 %, for biochemistry, 500 mg, glass
What is this article?
Dimidium bromide, min. 95 %, for biochemistry, 500 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
