Description
L(+)-Tartaric acid is a high-purity organic acid with a minimum assay of 99,7 %, intended for biochemistry. It carries CAS number 87-69-4, EG number 201-766-0 and the empirical formula C₄H₆O₆, with a molar mass of 150,09 g/mol and a density of 1,76 g/cm³. The boiling point is 179,1 °C and the flash point lies above 100 °C. This optically active enantiomer is valued as a complexing agent in analytical chemistry and complexometry, and supports biochemical workflows that need a reliable chiral hydroxy acid. Defined physical data help ensure reproducible solution making in research and quality-control laboratories. Within analytical chemicals and complexing-agent applications, L(+)-tartaric acid remains a standard reagent for metal-ion complexation and related methods requiring consistent purity and documented identity.

Questions about L(+)-Tartaric acid, min. 99.7 %, for biochemistry, 1 kg, plastic
What is this article?
L(+)-Tartaric acid, min. 99.7 %, for biochemistry, 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.
