Description
Rose bengal lactone is a biochemical compound specified by CAS number 4159-77-7 and empirical formula C₂₀H₄Cl₄I₄O₅. Its molar mass is 973,67 g/mol, providing a solid basis for stoichiometric calculations, solution preparation, and analytical documentation in the laboratory. This offer covers size, well suited to method development, small-scale experimental series, and reference applications where only limited material is required. Identity data including the CAS number, halogen-rich molecular formula, and molar mass support unambiguous labelling, inventory entry, and cross-checks against internal quality records. The product is available from manufacturer Carl ROTH within chemical and biochemical ranges oriented toward campaign and new-product highlights. Clear molecular descriptors facilitate integration into electronic notebooks, weighing protocols, and reagent logs without speculative performance claims. Together, the defined chemical identity and practical pack size make this Rose bengal lactone listing a straightforward choice for structured research use that depends on traceable specifications.

Questions about Rose bengal lactone, 250 mg
What is this article?
Rose bengal lactone, 250 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dehydrated culture media (agar & broth bases), inside Culture media & microbiology, in Life Science & Microbiology.
A dehydrated medium is a powder the laboratory dissolves, sterilises and pours. The formulation name, the supplements it still needs, and the grams per litre are the specification. Two powders with similar names, one selective and one not, grow different organisms.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
