Description
D-Asparagine is a biochemistry-grade amino acid derivative supplied at a minimum purity of 98 % for research and analytical use. It carries CAS number 5794-24-1 and EG nr. 218-163-3, with the empirical formula C₄H₈N₂O₃ · H₂O and a molar mass of 150,12 g/mol. The monohydrate form is convenient for stock solutions, media supplements and stereochemical studies that require the D-enantiomer rather than the more common L-form. Clear identity data and defined purity support reproducible experiments in peptide chemistry, metabolic research and chiral comparison work. Handle according to standard laboratory practice for amino acid reagents and consult the accompanying safety documentation before use.
This article is part of Amino acids & peptides, in Organic chemicals & synthesis reagents.

Questions about D-Asparagine, min. 98 %, for biochemistry, 5 g, plastic
What is this article?
D-Asparagine, min. 98 %, for biochemistry, 5 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Amino acids & peptides, inside Organic chemicals & synthesis reagents, in Lab chemicals.
An amino acid or a peptide is specified by the sequence or the residue, the chirality, and for a peptide the purity and the salt form. L and D forms are different compounds. A trifluoroacetate salt and a hydrochloride salt weigh differently per mole of peptide.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
Which category should I open next?
