Description
D-Leucine is a biochemistry-grade amino acid offered at a minimum purity of 99 % for laboratory and research use. Identified by CAS number 328-38-1 and EG nr. 206-327-7, it has the empirical formula C₆H₁₃NO₂ and a molar mass of 131,2 g/mol. As the D-enantiomer of leucine, this reagent supports work that depends on defined stereochemistry, including peptide and protein studies, metabolic investigations and chiral synthesis. The material is supplied in a practical from manufacturer Carl ROTH, suited to method development, standards preparation and small-scale biochemical experiments. Its clear specification helps laboratories maintain consistency when enantiomeric identity and high assay purity are required. D-Leucine is a useful building block for enzyme assays, structure–activity work and comparative studies with the L-form. The compact pack size fits routine bench use while providing a well-characterised amino acid for reproducible biochemistry workflows.

Questions about D-Leucine, min. 99 %, for biochemistry, 5 g, plastic
What is this article?
D-Leucine, min. 99 %, 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?
The category is Organic chemicals & synthesis reagents. The sub-category is Amino acids & peptides. The catalogue is Lab chemicals.
