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 Perfluorocyclohexanecarboxylic acid.
Perfluorocyclohexanecarboxylic acid (CAS 374-88-9), molecular formula C7HF11O2 and molecular weight 326.06 g/mol, is a CATO reference standard with documented purity and traceability.
Perfluorocyclohexanecarboxylic acid (C7HF11O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
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.
