Chemical Structure
Description
4-Bromo-1-methyl-2-(pentyloxy)benzene (CAS 1309932-69-1) is a high-purity analytical reference standard with the molecular formula C12H17BrO and a molecular weight of 257.17 g/mol.
Structurally, 4-Bromo-1-methyl-2-(pentyloxy)benzene (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.
As a certified reference material (CRM), 4-Bromo-1-methyl-2-(pentyloxy)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
