Chemical Structure
Description
The occurrence of 1,3-Diphenylbenzo[f]chromen-4-ium tetrafluoroborate is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Diphenylbenzo[f]chromen-4-ium tetrafluoroborate (CAS 35096-74-3), molecular formula C25H17OBF4 and molecular weight 420.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3-Diphenylbenzo[f]chromen-4-ium tetrafluoroborate (C25H17OBF4) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 420.21 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 1,3-Diphenylbenzo[f]chromen-4-ium tetrafluoroborate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
