Chemical Structure
Description
The occurrence of 1-Bromo-3-(cyclopropylmethyl)-5-methylbenzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-3-(cyclopropylmethyl)-5-methylbenzene (CAS 1369877-39-3), molecular formula C11H13Br and molecular weight 225.12 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H13Br, 1-Bromo-3-(cyclopropylmethyl)-5-methylbenzene contains bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
