Chemical Structure
Description
The occurrence of 3-(Chlorosulfonyl)-4-(hexadecyloxy)benzoic acid is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(Chlorosulfonyl)-4-(hexadecyloxy)benzoic acid (CAS 2488-47-3) is a high-purity analytical reference standard with the molecular formula C23H37ClO5S and a molecular weight of 461.05 g/mol.
3-(Chlorosulfonyl)-4-(hexadecyloxy)benzoic acid (C23H37ClO5S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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 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).
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.
CATO manufactures 3-(Chlorosulfonyl)-4-(hexadecyloxy)benzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
