2-Cyclopentylidene-2-fluoroacetic acid CAS 777946-22-2

Description

Compared with other compounds in its class, the molecular weight of 144.14 g/mol gives 2-Cyclopentylidene-2-fluoroacetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Cyclopentylidene-2-fluoroacetic acid (CAS 777946-22-2), a certified reference material (molecular formula C7H9FO2, MW 144.14 g/mol) for analytical method development and quality control.

2-Cyclopentylidene-2-fluoroacetic acid (C7H9FO2) 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.

As a certified reference material (CRM), 2-Cyclopentylidene-2-fluoroacetic 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.
