Chemical Structure
Description
The occurrence of Trans-1-(bromomethyl)-4-methylcyclohexane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Trans-1-(bromomethyl)-4-methylcyclohexane (CAS 78507-26-3), a certified reference material (molecular formula C8H15Br, MW 191.11 g/mol) for analytical method development and quality control.
Trans-1-(bromomethyl)-4-methylcyclohexane (C8H15Br) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
