Chemical Structure
Description
The occurrence of D-Tryptophan Methyl Ester Hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
D-Tryptophan Methyl Ester Hydrochloride (CAS CATO-C4X-137348), molecular formula C12H16N2O2HCl and molecular weight 256.73 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H16N2O2HCl, D-Tryptophan Methyl Ester Hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
