Chemical Structure
Description
2-{2-[(4-phenylphenyl)methylidene]hydrazin-1-yl}-1,3-benzoxazole (C20H15N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
2-{2-[(4-phenylphenyl)methylidene]hydrazin-1-yl}-1,3-benzoxazole (CAS 454225-95-7), molecular formula C20H15N3O and molecular weight 313.35 g/mol, is a CATO reference standard with documented purity and traceability.
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.
