Description
Stearic acid is a long-chain saturated fatty acid offered at minimum 98 % purity for general laboratory and formulation work. It carries CAS 57-11-4 and EG nr. 200-313-4, empirical formula C₁₈H₃₆O₂, molar mass 284,47 g/mol and density 0,87 g/cm³. Physical data include a flash point of 200 °C and a boiling range from ≥383 to ≤385,8 °C, supporting safe process planning in heated applications. Laboratories value its defined assay and well-characterised thermal profile when preparing standards or intermediate blends. Use under standard organic-acid handling practice with appropriate personal protection and ventilation during melting or dissolution steps.
This article is part of Acids, in Acids & bases.

Questions about Stearic acid, min. 98 %, 1 kg, plastic
What is this article?
Stearic acid, min. 98 %, 1 kg, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
