2-fluorocyclobutane-1-carboxylic acid CAS 1785331-71-6

Description

2-fluorocyclobutane-1-carboxylic acid (CAS 1785331-71-6), molecular formula C5H7FO2 and molecular weight 118.11 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-fluorocyclobutane-1-carboxylic acid (C5H7FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 118.11 g/mol, it falls into the low-molecular-weight range. 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-fluorocyclobutane-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.
