Description
L-Arginine is a high-purity amino acid offered at min. 99 % in CELLPURE® quality for cell culture and related biochemical work. It is defined by CAS number 74-79-3, empirical formula C₆H₁₄N₄O₂ and a molar mass of 174,2 g/mol, with density in the range 1,36 to 1,56 g/cm³. These identity data support reliable use wherever a clearly specified L-arginine source is required. The product is Sourced from manufacturer Carl ROTH, it also carries EG nr. 200-811-1 and fits applications listed under amino acids for cell culture. Consistent purity and documented physicochemical parameters help laboratories maintain reproducible workflows in research and production environments that depend on controlled amino acid quality.

Questions about L-Arginine, min. 99 %, CELLPURE®, 25 g, plastic
What is this article?
L-Arginine, min. 99 %, CELLPURE®, 25 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Biochemicals & reagents, in Life Science & Microbiology.
Click and bioconjugation reagents join two molecules under mild conditions, often an azide to an alkyne, or an NHS ester to an amine. The linker length and the reactive group are the specification. They are small bottles of a reactive compound, and moisture often ruins them.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
