Chemical Structure

1,1-difluorocycloheptane CAS 27371-42-2 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 1,1-difluorocycloheptane.

CATO supplies 1,1-difluorocycloheptane (CAS 27371-42-2), a certified reference material (molecular formula C7H12F2, MW 134.17 g/mol) for analytical method development and quality control.

1,1-difluorocycloheptane (C7H12F2) contains fluorine substitution. Halogen substitution raises its density and boiling point; 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.
