Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 256.69 g/mol gives (S)-2-Amino-3-(5-hydroxy-1H-indol-3-yl)propanoic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-2-Amino-3-(5-hydroxy-1H-indol-3-yl)propanoic acid hydrochloride (CAS 17469-40-8), molecular formula C11H12N2O3HCl and molecular weight 256.69 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (S)-2-Amino-3-(5-hydroxy-1H-indol-3-yl)propanoic acid hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
