Chemical Structure
Description
A23187, 4-Bromo (CAS 76455-48-6), molecular formula C29H36BrN3O6 and molecular weight 602.52 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, A23187, 4-Bromo is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 602.52 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
