Questions about b-Estradiol, 50 g
What is this article?
b-Estradiol, 50 g 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.
