Description
L-Aspartic acid is an amino acid reagent supplied at min. 98.5 % purity according to Ph. Eur., intended for biochemistry applications. It is identified by CAS number 56-84-8 and EG number 200-291-6, with empirical formula C₄H₇NO₄, a molar mass of 133,1 g/mol, and a density of 1,66 g/cm³. from manufacturer Carl ROTH suits preparation of buffers, culture media components, calibration solutions, and other biochemical working reagents where a pharmacopoeial-grade L-enantiomer is specified. Laboratories engaged in protein chemistry, metabolic studies, or method development can rely on this material as a defined building-block amino acid. Its documented purity and physical data support transparent documentation in research and quality-controlled biochemical workflows without additional formulation steps beyond standard laboratory practice.

Questions about L-Aspartic acid, min. 98.5 %, Ph. Eur., for biochemistry, 100 g, plastic
What is this article?
L-Aspartic acid, min. 98.5 %, Ph. Eur., for biochemistry, 100 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?
