Chemical Structure
Description
The occurrence of (5-Bromo-2-methoxyphenyl)methyl 4-tert-butylbenzoate 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.
CATO supplies (5-Bromo-2-methoxyphenyl)methyl 4-tert-butylbenzoate (CAS 331460-30-1), a certified reference material (molecular formula C19H21BrO3, MW 377.27 g/mol) for analytical method development and quality control.
(5-Bromo-2-methoxyphenyl)methyl 4-tert-butylbenzoate (C19H21BrO3) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 (5-Bromo-2-methoxyphenyl)methyl 4-tert-butylbenzoate 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.
