1-Bromo-4,4-dimethylcyclohex-1-ene CAS 1020253-13-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-4,4-dimethylcyclohex-1-ene.

1-Bromo-4,4-dimethylcyclohex-1-ene (CAS 1020253-13-7) is a high-purity analytical reference standard with the molecular formula C8H13Br and a molecular weight of 189.09 g/mol.

The molecular framework of 1-Bromo-4,4-dimethylcyclohex-1-ene (C8H13Br) 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.
