Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Bis(trifluoromethyl)cyclohexane (cis- and trans- mixture).
1,4-Bis(trifluoromethyl)cyclohexane (cis- and trans- mixture) (CAS 433-18-1) is a high-purity analytical reference standard with the molecular formula C8H10F6 and a molecular weight of 220.16 g/mol.
Owing to fluorine substitution, 1,4-Bis(trifluoromethyl)cyclohexane (cis- and trans- mixture) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
