Chemical Structure
Description
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.
Methyl 4-((1,3,3-trimethyl-6-azabicyclo-[3.2.1]octan-6-yl)sulfonyl)benzoate (CAS 1628466-33-0) is a high-purity analytical reference standard with the molecular formula C18H25NO4S and a molecular weight of 351.46 g/mol.
The molecular framework of Methyl 4-((1,3,3-trimethyl-6-azabicyclo-[3.2.1]octan-6-yl)sulfonyl)benzoate (C18H25NO4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. 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).
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.
