Chemical Structure
Description
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.
(4-(Bis(4-(tert-butyl)phenyl)amino)phenyl)boronic acid (CAS 851233-24-4), molecular formula C26H32BNO2 and molecular weight 401.35 g/mol, is a CATO reference standard with documented purity and traceability.
(4-(Bis(4-(tert-butyl)phenyl)amino)phenyl)boronic acid (C26H32BNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures (4-(Bis(4-(tert-butyl)phenyl)amino)phenyl)boronic acid 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.
