L-Tyrosine disodium salt dihydrate is a water-soluble sodium salt of the amino acid tyrosine, widely used in pharmaceuticals, nutraceuticals, and biochemical research as a precursor for dopamine, norepinephrine, and epinephrine synthesis, as well as in protein labeling and peptide synthesis. It appears as a white to off-white crystalline powder with high purity and solubility. This compound has a CAS number of 122666-87-9, a molecular formula of C9H9NO3·2Na·2H2O, and a molecular weight of 261.18 g/mol. It is stable at ambient storage conditions but requires careful handling due to its hazardous classification (Signal Word: Danger). Molekula supplies L-Tyrosine disodium salt dihydrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
