Chemical Structure

1-Bromocyclohept-1-ene CAS 18317-64-1 chemical structure

Description

The occurrence of 1-Bromocyclohept-1-ene is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromocyclohept-1-ene (CAS 18317-64-1) is a high-purity analytical reference standard with the molecular formula C7H11Br and a molecular weight of 175.07 g/mol.

The molecular framework of 1-Bromocyclohept-1-ene (C7H11Br) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
