Description
L-Ornithine monohydrochloride is a biochemistry-grade amino acid salt with a minimum purity of 99 %. Characterised by the empirical formula C₅H₁₂N₂O₂ · HCl, a molar mass of 168,62 g/mol and a density of 1,429 g/cm³, it is identified by CAS number 3184-13-2 and EG nr. 221-678-6. This monohydrochloride form is commonly used in metabolic research, urea-cycle studies and the preparation of specialised culture or assay media. Its defined composition and high minimum assay support consistent results in research protocols that require L-ornithine as a free amino acid salt.

Questions about L-Ornithin monohydrochloride, min. 99 %, for biochemistry, 25 g, plastic
What is this article?
L-Ornithin monohydrochloride, min. 99 %, for biochemistry, 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.
