Description
DL-Methionine (CAS 59-51-8) is an amino acid reagent supplied at a minimum purity of 99 % for biochemistry applications. It has the empirical formula C₅H₁₁NO₂S, a molar mass of 149,21 g/mol and a density of 1,34 g/cm³. This racemic methionine is In biochemical laboratories it serves as a sulphur-containing amino acid standard, a medium component and a building block for peptide or metabolic studies. The grade from manufacturer Carl ROTH carries EG number 200-432-1 and is intended for controlled laboratory use rather than bulk industrial processing. Its defined purity supports reproducible preparation of buffers, culture supplements and reference solutions. Researchers working in protein chemistry, nutrition models or enzymatic assays can rely on consistent material identity and composition. The compact pack size is practical for method development, teaching practicals and small-scale synthesis where accurate weighing and clean handling are essential.
This article belongs on Microscopy stains & staining solutions, in Dyes, stains & indicators.

Questions about DL-Methionine, min. 99 %, for biochemistry, 100 g, plastic
What is this article?
DL-Methionine, min. 99 %, for biochemistry, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Microscopy stains & staining solutions, inside Dyes, stains & indicators, in Lab chemicals.
A microscopy stain binds a structure so it can be seen: haematoxylin on nuclei, eosin on cytoplasm, Gram reagents on a bacterial wall. A ready solution and a dry dye to be dissolved are different articles. The method names the stain. A substitute dye is a different method.
A dye or a stain binds, or changes colour, so that something invisible becomes visible. An indicator changes at a pH or a redox point. A fluorescent dye absorbs one wavelength and emits another, which is how a microscope or a plate reader picks it out. The excitation and emission, or the transition interval, are the specification. The colour name on the label is not. Structures are on PubChem under IUPAC names. Methods are in the PubMed literature.
