Chemical Structure
Description
(2S)-2-Amino-2-(3-bromophenyl)ethanol (CAS 209963-05-3), molecular formula C8H10BrNO and molecular weight 216.08 g/mol, is a CATO reference standard with documented purity and traceability.
(2S)-2-Amino-2-(3-bromophenyl)ethanol (C8H10BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
