Chemical Structure
Description
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.
(S)-2-Amino-2-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)ethan-1-ol (CAS 1212972-65-0) is a high-purity analytical reference standard with the molecular formula C10H13NO3 and a molecular weight of 195.22 g/mol.
(S)-2-Amino-2-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)ethan-1-ol (C10H13NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
