Chemical Structure
Description
The occurrence of 1-(2-Bromoethyl)-3,5-dimethylbenzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(2-Bromoethyl)-3,5-dimethylbenzene (CAS 93427-11-3), a certified reference material (molecular formula C10H13Br, MW 213.11 g/mol) for analytical method development and quality control.
Structurally, 1-(2-Bromoethyl)-3,5-dimethylbenzene (C10H13Br) contains 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 213.11 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
