Description
D(-)-Tartaric acid is a high-purity chiral organic acid supplied at min. 99 % for biochemistry applications. With CAS number 147-71-7 and empirical formula C₄H₆O₆, it has a molar mass of 150,09 g/mol and a density of 1,8 g/cm³. The flash point is 210 °C. This stereoisomer is widely used in complexometric work, chiral resolution, buffer systems and as a complexing agent in analytical and biochemical laboratories. Packaged as 25 g in plastic, the material from manufacturer Carl ROTH offers a practical laboratory quantity for method development and routine assays. Its defined optical configuration and documented purity support reproducible results in titration, metal-ion complexation and related analytical workflows. Suitable for research and quality-control environments that require a reliable D-configured tartaric acid grade without unnecessary additives.
This article is part of Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about D(-)-Tartaric acid, min. 99 %, for biochemistry, 25 g, plastic
What is this article?
D(-)-Tartaric acid, min. 99 %, for biochemistry, 25 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
