2-Bromo-7-chlorohept-1-ene CAS 485320-15-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-7-chlorohept-1-ene.

2-Bromo-7-chlorohept-1-ene (CAS 485320-15-8), molecular formula C7H12BrCl and molecular weight 211.53 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Bromo-7-chlorohept-1-ene (C7H12BrCl) contains chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 211.53 g/mol, it falls into the medium-molecular-weight range. 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.
