Chemical Structure
Description
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.
6,6'-Methylenebis(4-(tert-butyl)-2-methylphenol) (CAS 3634-86-4), molecular formula C23H32O2 and molecular weight 340.50 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C23H32O2, 6,6'-Methylenebis(4-(tert-butyl)-2-methylphenol) contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
