Description
L-Tryptophane, min. 99 %, CELLPURE® is a high-purity amino acid supplied for cell-culture applications and related laboratory formulation work. It is identified by CAS number 73-22-3 and empirical formula C₁₁H₁₂N₂O₂, with a molar mass of 204,23 g/mol. Specified at minimum 99 % purity and listed under EG nr. 200-795-6, the material is This CELLPURE® grade amino acid from manufacturer Carl ROTH supports preparation of culture media and nutrient mixes where defined L-tryptophane content is required. Laboratories can incorporate the solid into buffered systems following standard cell-culture protocols. size suits method development, stock replenishment, and routine media work that depends on consistent amino-acid quality. Clear chemical identity, assay level, and pack format make it a practical choice for research and production environments focused on controlled culture formulations.

Questions about L-Tryptophane, min. 99 %, CELLPURE®, 25 g, plastic
What is this article?
L-Tryptophane, min. 99 %, CELLPURE®, 25 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.
