Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Bromo-1-(isopentyloxy)ethyl)-2-methylbenzene.
1-(2-Bromo-1-(isopentyloxy)ethyl)-2-methylbenzene (CAS 1248041-84-0) is a high-purity analytical reference standard with the molecular formula C14H21BrO and a molecular weight of 285.22 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1-(2-Bromo-1-(isopentyloxy)ethyl)-2-methylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
