Chemical Structure
Description
The occurrence of 478048-04-3 4R-1325 [(4Z)-4,5,6,7-tetrahydro-1-benzofuran-4-ylidene]amino 4-chlorobenzene-1-sulfonate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
478048-04-3 4R-1325 [(4Z)-4,5,6,7-tetrahydro-1-benzofuran-4-ylidene]amino 4-chlorobenzene-1-sulfonate (CAS 478048-04-3) is a high-purity analytical reference standard with the molecular formula C14H12ClNO4S and a molecular weight of 325.77 g/mol.
478048-04-3 4R-1325 [(4Z)-4,5,6,7-tetrahydro-1-benzofuran-4-ylidene]amino 4-chlorobenzene-1-sulfonate (C14H12ClNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
