Chemical Structure
Description
1-bromo-5-(tert-butyl)-4-methoxy-2-methylbenzene (CAS 26822-00-4) is a high-purity analytical reference standard with the molecular formula C12H17BrO and a molecular weight of 257.17 g/mol.
Structurally, 1-bromo-5-(tert-butyl)-4-methoxy-2-methylbenzene (C12H17BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 257.17 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.
