Chemical Structure

5,7-Di-tert-butyl-3-(3,5-dimethylphenyl)benzo[d]oxazol-3-ium tetrafluoroborate CAS 2750161-98-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,7-Di-tert-butyl-3-(3,5-dimethylphenyl)benzo[d]oxazol-3-ium tetrafluoroborate.

CATO supplies 5,7-Di-tert-butyl-3-(3,5-dimethylphenyl)benzo[d]oxazol-3-ium tetrafluoroborate (CAS 2750161-98-7), a certified reference material (molecular formula C23H30NOBF4, MW 423.30 g/mol) for analytical method development and quality control.

5,7-Di-tert-butyl-3-(3,5-dimethylphenyl)benzo[d]oxazol-3-ium tetrafluoroborate (C23H30NOBF4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
