Description

Compared with other compounds in its class, the molecular weight of 197.19 g/mol gives 2-Amino-3-hydroxy-3-(4-hydroxyphenyl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Amino-3-hydroxy-3-(4-hydroxyphenyl)propanoic acid (CAS 6809-69-4) is a high-purity analytical reference standard with the molecular formula C9H11NO4 and a molecular weight of 197.19 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-Amino-3-hydroxy-3-(4-hydroxyphenyl)propanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.19 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
