Description
Lecithin with a minimum purity of 97 % is a soybean-derived phospholipid preparation intended for biochemistry. It is identified by CAS number 8002-43-5 and EG number 232-307-2, with a density below 1 g/cm³. This grade is used as a nutrient media additive and in broader life-science workflows where a defined lecithin source is required. The material is Made from soybeans, it suits culture media formulation, emulsion studies and related experimental preparations. Application data and specifications from manufacturer Carl ROTH support straightforward integration into existing protocols and quality documentation. Research groups working in microbiology and nutrient media development can rely on the stated minimum purity for reproducible batch preparation. The plastic pack protects the product during storage and handling on the bench. Consistent composition helps maintain reliable performance whenever lecithin is specified as a media component or biochemical reagent in routine laboratory practice.

Questions about Lecithin, min. 97 %, made from soybeans, for biochemistry, 250 g, plastic
What is this article?
Lecithin, min. 97 %, made from soybeans, for biochemistry, 250 g, plastic 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.
