Description
Stigmasterol is a plant sterol reference material with a minimum assay of 95 %, intended for analytical chemistry and phytochemical applications. It is identified by CAS number 83-48-7 and EG number 201-482-7, with the empirical formula C₂₉H₄₈O and a molar mass of 412,70 g/mol. The substance is packed as 1 g in glass, providing a practical quantity for calibration solutions, identity confirmation and comparative chromatographic studies. Stigmasterol occurs widely in vegetable oils and plant tissues and is frequently selected as a marker when laboratories profile sterol fractions or characterise natural-product extracts. Available from manufacturer Carl ROTH, this material supports research and quality-control environments that depend on defined phytosterol standards. Placement among analytical chemicals, chromatography standards and phytochemicals underlines its role in method development and reliable sample characterisation involving plant sterols.

Questions about Stigmasterol, min. 95 %, 1 g, glass
What is this article?
Stigmasterol, min. 95 %, 1 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Lipids, steroids & fatty acids, inside Biochemicals & reagents, in Life Science & Microbiology.
A lipid, a steroid or a fatty acid is specified by chain length, saturation and purity. Esters and free acids are different compounds. Many are supplied in a small amount under inert gas because they oxidise. The physical form, oil or powder, follows from the structure.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
