Description

The occurrence of N-{9-acetyl-2-oxa-9-azatricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3,5,7,12,14-hexaen-13-yl}-4-bromobenzene-1-sulfonamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-{9-acetyl-2-oxa-9-azatricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3,5,7,12,14-hexaen-13-yl}-4-bromobenzene-1-sulfonamide (CAS 866157-26-8) is a high-purity analytical reference standard with the molecular formula C21H17BrN2O4S and a molecular weight of 473.34 g/mol.

The molecular framework of N-{9-acetyl-2-oxa-9-azatricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3,5,7,12,14-hexaen-13-yl}-4-bromobenzene-1-sulfonamide (C21H17BrN2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
