Chemical Structure
Description
The molecular framework of 4,4'-Dimethoxybenzhydrol 4-Methoxy-4'-methoxybenzhydrol 728-87-0 Benzenemethanol, 4-methoxy-.alpha.-(4-methoxyphenyl)- Benzhydrol,4'-dimethoxy- Bis(p-methoxyphenyl)carbinol NSC-5256 NSC5256 p,p'-Dimethoxybenzhydrol (C15H28O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4,4'-Dimethoxybenzhydrol 4-Methoxy-4'-methoxybenzhydrol 728-87-0 Benzenemethanol, 4-methoxy-.alpha.-(4-methoxyphenyl)- Benzhydrol,4'-dimethoxy- Bis(p-methoxyphenyl)carbinol NSC-5256 NSC5256 p,p'-Dimethoxybenzhydrol (CAS 728-87-0) is a high-purity analytical reference standard with the molecular formula C15H28O3 and a molecular weight of 256.38 g/mol.
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.
