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-(3-methoxypropoxy)ethyl)-4-methylbenzene.
CATO supplies 1-(2-Bromo-1-(3-methoxypropoxy)ethyl)-4-methylbenzene (CAS 1249388-98-4), a certified reference material (molecular formula C13H19BrO2, MW 287.19 g/mol) for analytical method development and quality control.
Structurally, 1-(2-Bromo-1-(3-methoxypropoxy)ethyl)-4-methylbenzene (C13H19BrO2) contains a carboxylic acid group, 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 287.19 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
