Description
5β-Androstan-3,17-dione is an androstane diketone supplied at a minimum purity of 95 % for biochemical and steroid-chemistry applications. With CAS number 1229-12-5 and the empirical formula C₁₉H₂₈O₂, the compound has a molar mass of 288,42 g/mol. This androstane derivative is offered by manufacturer Carl ROTH within its biochemicals range and is selected when a high-purity steroid dione of defined identity is needed. Investigators employ the material in metabolic studies, chromatographic reference work and the preparation of related androstane structures. Documented molar mass and formula data enable precise mass calculation and reproducible solution make-up. The combination of stated purity and clear molecular identity supports reliable use in method development, structure–activity exploration and routine laboratory practice across chemical and life-science settings focused on steroid research.

Questions about 5b-Androstan-3,17-dione, min. 95 %, 10 mg
What is this article?
5b-Androstan-3,17-dione, min. 95 %, 10 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Spectroscopy & physical property standards, inside Analytical standards & reference materials, in Lab chemicals.
These standards check a physical or optical measurement: a refractive-index liquid, a wavelength standard, a viscosity oil, a melting-point substance. The stated value and its uncertainty are the product. They are not general reagents.
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.
