Description
17a-Estradiol is a steroidal biochemical supplied at a minimum purity of 95 % for laboratory research applications. The compound is identified by CAS number 57-91-0, empirical formula C₁₈H₂₄O₂, and a molar mass of 272,38 g/mol, providing the core data needed for identity confirmation and quantitative work. It is offered in a 10 g pack size that supports repeated experimental use, stock solution preparation, and comparative studies in chemical and biochemical settings. Clear molecular and assay information aids stoichiometric calculations, chromatographic method setup, and documentation of reference materials. This grade is available from manufacturer Carl ROTH as part of a biochemicals portfolio aimed at professional laboratory handling. Researchers can rely on the stated purity and formula when designing assays, calibration materials, or synthetic sequences that involve estradiol isomers. The convenient unit quantity balances working stock with controlled consumption, helping laboratories maintain consistent supply of 17a-estradiol under defined specification without unnecessary surplus.

Questions about 17a-Estradiol, min. 95 %, 25 g
What is this article?
17a-Estradiol, min. 95 %, 25 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 Microbiology lab supplies.
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.
