7-Bromo-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine 95897-49-7 MFCD15530247 SY045906 (CAS 95897-49-7), molecular formula C7H12BrNO2 and molecular weight 222.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Bromo-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine 95897-49-7 MFCD15530247 SY045906 (C7H12BrNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
