Chemical Structure
Description
7-(1H-pyrrol-1-yl)-2,3-dihydrobenzo[b][1,4]dioxin-6-amine (CAS 879045-10-0), molecular formula C12H12N2O2 and molecular weight 216.24 g/mol, is a CATO reference standard with documented purity and traceability.
7-(1H-pyrrol-1-yl)-2,3-dihydrobenzo[b][1,4]dioxin-6-amine (C12H12N2O2) 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.
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.
