Description
Curcumin is a natural diarylheptanoid supplied at a minimum purity of 90 % as an oil-soluble powder for laboratory applications. Identified by CAS number 458-37-7 and EG number 207-280-5, it has the empirical formula C₂₁H₂₀O₆ and a molar mass of 368,39 g/mol. The preparation is Curcumin is valued for its intense yellow colouration and is routinely used when laboratories formulate pH indicator solutions or examine polyphenolic constituents linked to turmeric and related plant materials. Available from manufacturer Carl ROTH, the substance supports research and quality-control environments that need a consistent curcumin grade. Categorisation under indicators, pH indicators and analytical chemicals highlights its dual role in colourimetric assays and chromatographic characterisation of curcuminoids.

Questions about Curcumin, min. 90 %,, naturally, powdered, oil-soluble, 10 g, glass
What is this article?
Curcumin, min. 90 %,, naturally, powdered, oil-soluble, 10 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?
