Chemical Structure
Description
The occurrence of tert-Butyl 3-bromo-2-((tert-butoxycarbonyl)oxy)-6-methoxybenzoate is closely related to a steroid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl 3-bromo-2-((tert-butoxycarbonyl)oxy)-6-methoxybenzoate (CAS 1830305-97-9), molecular formula C17H23BrO6 and molecular weight 403.26 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 3-bromo-2-((tert-butoxycarbonyl)oxy)-6-methoxybenzoate (C17H23BrO6) contains a steroid core, a hydroxyl group, an ether linkage, bromine 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 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.
