Chemical Structure
Description
The occurrence of Bromo-Rupatadine fumarate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Bromo-Rupatadine fumarate (CAS 1332619-71-2(free base)) is a high-purity analytical reference standard with the molecular formula C26H26BrN3C4H4O4 and a molecular weight of 576.49 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Bromo-Rupatadine fumarate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 576.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Bromo-Rupatadine fumarate 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.
