Description
L-Arginine monohydrochloride is a CELLPURE® amino acid salt supplied at a minimum purity of 98,5 % for demanding cell-culture and biochemical work. Identified by CAS number 1119-34-2 and EG nr. 214-275-1, it has the empirical formula C₆H₁₄N₄O₂ · HCl, a molar mass of 210,67 g/mol and a density of 1,42 g/cm³, with a boiling point of 235 °C. This provides a convenient laboratory quantity of the monohydrochloride form of L-arginine, a basic amino acid routinely used in media formulation, metabolic studies and protein-related research. Offered from manufacturer Carl ROTH under the CELLPURE® grade, the material supports controlled preparation of culture supplements and analytical standards where defined composition and high purity are required. Its physical data and documented identity make it suitable for reproducible workflows in cell biology, nutrition research and general organic chemistry applications that rely on well-characterised amino acid building blocks.

Questions about L-Arginine monohydrochloride, min. 98,5 %, CELLPURE®, 25 g, plastic
What is this article?
L-Arginine monohydrochloride, min. 98,5 %, 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.
