Chemical Structure
Description
The occurrence of 3,3-Difluorocycloheptane-1-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,3-Difluorocycloheptane-1-carboxylic acid (CAS 1934431-40-9), molecular formula C8H12F2O2 and molecular weight 178.18 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H12F2O2, 3,3-Difluorocycloheptane-1-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 178.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 3,3-Difluorocycloheptane-1-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
