Chemical Structure

4,4’-(Propane-2,2-diyl)bis(2-allylphenol) CAS 1745-89-7 chemical structure

Description

The occurrence of 4,4’-(Propane-2,2-diyl)bis(2-allylphenol) is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,4’-(Propane-2,2-diyl)bis(2-allylphenol) (CAS 1745-89-7), a certified reference material (molecular formula C21H24O2, MW 308.41 g/mol) for analytical method development and quality control.

Structurally, 4,4’-(Propane-2,2-diyl)bis(2-allylphenol) (C21H24O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 308.41 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), 4,4’-(Propane-2,2-diyl)bis(2-allylphenol) 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.
