Chemical Structure
Description
(4-Bromophenyl)(2,4-dimethylphenyl)methanol (CAS 944645-40-3), molecular formula C15H15BrO and molecular weight 291.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4-Bromophenyl)(2,4-dimethylphenyl)methanol (C15H15BrO) contains a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 291.18 g/mol, it falls into the medium-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.
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.
