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 2-Bromo-4-methyl-1-(prop-2-en-1-yloxy)benzene.
CATO supplies 2-Bromo-4-methyl-1-(prop-2-en-1-yloxy)benzene (CAS 2120-18-5), a certified reference material (molecular formula C10H11BrO, MW 227.10 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-4-methyl-1-(prop-2-en-1-yloxy)benzene (C10H11BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
