Description
4-Pentenoic acid is an unsaturated aliphatic carboxylic acid offered at a minimum purity of 95 %, with CAS number 591-80-0 and empirical formula C₅H₈O₂. It has a molar mass of 100,12 g/mol, a density of 0,981 g/cm³, a flash point of 89 °C, and a boiling point of 83 °C. The terminal double bond combined with the carboxyl group makes this C₅ building block useful for organic synthesis, polymer modification, and the preparation of esters, amides, or other derivatives. It is listed with UN number 1760, reflecting standard transport classification for corrosive liquids of this type. Available from manufacturer Carl ROTH, the acid fits biochemical and fine-chemical workflows that require a defined unsaturated fatty-acid analogue. Physical constants provided with the product help laboratories plan safe handling, reaction design, and analytical verification during synthetic sequences.
This article is part of Acids, in Acids & bases.

Questions about 4-Pentenoic acid, min. 95 %, 50 g
What is this article?
4-Pentenoic acid, min. 95 %, 50 g 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.
