Description
As a certified reference material (CRM), Ethyl (2R)-2-amino-3-(3,4-dihydroxyphenyl)propanoate hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Ethyl (2R)-2-amino-3-(3,4-dihydroxyphenyl)propanoate hydrochloride (CAS 184489-03-0) is a high-purity analytical reference standard with the molecular formula C11H15NO4HCl and a molecular weight of 261.70 g/mol.
Based on its molecular formula C11H15NO4HCl, Ethyl (2R)-2-amino-3-(3,4-dihydroxyphenyl)propanoate 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 261.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
