Chemical Structure

6,6'-(1,4-Phenylenebis(propane-2,2-diyl))bis(2,4-dimethylphenol) CAS 34074-95-8 chemical structure

Description

Structurally, 6,6'-(1,4-Phenylenebis(propane-2,2-diyl))bis(2,4-dimethylphenol) (C28H34O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 402.57 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies 6,6'-(1,4-Phenylenebis(propane-2,2-diyl))bis(2,4-dimethylphenol) (CAS 34074-95-8), a certified reference material (molecular formula C28H34O2, MW 402.57 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
