Chemical Structure
Description
The occurrence of N,N-Dibutyl-3-methyl-2-oxo-2,3-dihydrobenzo[d]oxazole-6-sulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N,N-Dibutyl-3-methyl-2-oxo-2,3-dihydrobenzo[d]oxazole-6-sulfonamide (CAS 62522-64-9), molecular formula C16H24N2O4S and molecular weight 340.44 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N,N-Dibutyl-3-methyl-2-oxo-2,3-dihydrobenzo[d]oxazole-6-sulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
