Description
L-Tyrosine disodium salt hydrate is a water-compatible amino acid salt used in biochemical and cell-culture related laboratory work. It is registered under CAS number 69847-45-6 with the empirical formula C₉H₉NNa₂O₃·xH₂O and a molar mass of 225,15 g/mol. The disodium salt form improves handling and solubility relative to free L-tyrosine, supporting buffer preparation, media supplementation, and peptide or protein research workflows. This listing provides size suitable for routine laboratory consumption and scale-up of aqueous formulations. Identity and molar-mass data enable accurate stoichiometric dosing and documentation. The material is available from manufacturer Carl ROTH in its biochemicals assortment for professional scientific use. Researchers employ L-tyrosine salts in metabolic studies, formulation development, and as building blocks where the aromatic amino acid side chain is required in ionic form. Clear CAS and formula labelling assist quality systems, inventory tracking, and reproducible experimental design across biochemical applications.

Questions about L-Tyrosine disodium salt hydrate, 250 g
What is this article?
L-Tyrosine disodium salt hydrate, 250 g 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.
