Description
Pentaerythrityl tetrastearate is a high-purity ester mixture supplied at min. 95 % for laboratory and biochemical work. Identified by CAS number 115-83-3 and empirical formula C₇₇H₁₄₈O₈, it has a molar mass of 1202,01 g/mol. This long-chain tetraester of pentaerythritol and stearic acid is used in formulation studies, lipid chemistry, and as a reference or intermediate in organic and materials research. The material is offered as a defined mixture grade suitable for controlled experimental setups where consistent ester composition is required. Available from manufacturer Carl ROTH, the product fits chemical and biochemical workflows that call for a well-characterised stearate ester. Clear CAS and formula data facilitate inventory control, safety documentation, and reproducible preparation of stock materials in research and quality environments.

Questions about Pentaerythrityl tetrastearate, min. 95 %, mixture, 250 g
What is this article?
Pentaerythrityl tetrastearate, min. 95 %, mixture, 250 g 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.
