Description
Zinc iodide is a high-assay inorganic salt supplied as a powder with a minimum content of 98 %. It carries CAS number 10139-47-6 and empirical formula ZnI₂, with a molar mass of 319,18 g/mol and a density of 4,74 g/cm³. The boiling point is stated as 625 °C. EG number 233-396-0 and UN number 3077 complete the principal regulatory identifiers. This reagent is relevant to water-analysis workflows, including biological oxygen demand (BOD) applications where zinc iodide is specified in laboratory protocols. Powder form and the defined minimum assay support accurate weighing and solution preparation. Data from manufacturer Carl ROTH enable straightforward integration into analytical methods that require a characterised zinc iodide source. is sized for method development, calibration work, and routine BOD-related testing without excess bulk, while density and molar-mass values assist stoichiometric calculations in aqueous analytical chemistry.
This article belongs on Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about Zinc iodide, min. 98 %, powder, 25 g, glass
What is this article?
Zinc iodide, min. 98 %, powder, 25 g, 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.
