Description
5α-Pregnan-3α-ol-20-one is a pregnane steroid of established interest in biochemical, neurosteroid and endocrinology research programmes. The compound is identified by CAS number 516-54-1 and possesses the empirical formula C₂₁H₃₄O₂ together with a molar mass of 318,49 g/mol. It is supplied in a convenient 250 mg pack that provides a practical quantity for assay development, reference standard preparation and exploratory synthetic work. This well-characterised steroidal alcohol-ketone is available from manufacturer Carl ROTH as part of the biochemicals portfolio. Laboratories rely on its defined molecular identity when preparing calibration standards, studying metabolic pathways or elaborating related steroid scaffolds under controlled conditions. The material supports chromatographic method set-up, receptor-oriented studies and broader investigations into pregnane chemistry and signalling. Clear documentation of molar mass and empirical formula assists accurate weighing and solution preparation, helping researchers maintain consistency from stock formulation through to experimental readout across chemical biology and life-science laboratory environments focused on steroid research.

Questions about 5α-Pregnan-3α-ol-20-one
What is this article?
5α-Pregnan-3α-ol-20-one is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
