Chemical Structure
Description
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.
1-(Bromomethyl)-1-isopentylcyclopentane (CAS 1489287-35-5), molecular formula C11H21Br and molecular weight 233.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, 1-(Bromomethyl)-1-isopentylcyclopentane is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 233.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
