Description
L(+)-Tartaric acid is a high-purity organic acid supplied at a minimum assay of 99,5 % and conforming to Ph.Eur. quality requirements. Identified by CAS number 87-69-4 and EG number 201-766-0, the compound has the empirical formula C₄H₆O₆, a molar mass of 150,09 g/mol and a density of 1,76 g/cm³. Further physical data include a boiling point of 179,1 °C and a flash point above 100 °C, supporting controlled handling under standard laboratory conditions. Typical uses include buffer preparation, chiral chemistry support and quality-control procedures where a defined L-enantiomer is required. Laboratories value the consistent specification for reproducible results across research and production environments. This material from manufacturer Carl ROTH provides a dependable source of L(+)-tartaric acid for routine weighing and formulation tasks. The plastic pack format facilitates straightforward storage and dispensing within chemical inventories.

Questions about L(+)-Tartaric acid, min. 99,5 %, Ph.Eur., 500 g, plastic
What is this article?
L(+)-Tartaric acid, min. 99,5 %, Ph.Eur., 500 g, 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.
Which category should I open next?
