Chemical Structure
Description
3-Cyclopropoxy-N-methyl-2-(methylsulfonamido)benzamide (CAS 1243379-86-3) is a high-purity analytical reference standard with the molecular formula C12H16N2O4S and a molecular weight of 284.33 g/mol.
3-Cyclopropoxy-N-methyl-2-(methylsulfonamido)benzamide (C12H16N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
