Chemical Structure
Description
The occurrence of (1S,4s)-1-(bromomethyl)-4-methylcyclohexane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(1S,4s)-1-(bromomethyl)-4-methylcyclohexane (CAS 78507-33-2) is a high-purity analytical reference standard with the molecular formula C8H15Br and a molecular weight of 191.11 g/mol.
(1S,4s)-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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
