3-Fluoro-2-methylpropene CAS 920-35-4 chemical structure

Description

3-Fluoro-2-methylpropene (CAS 920-35-4) is a high-purity analytical reference standard with the molecular formula C4H7F and a molecular weight of 74.10 g/mol.

3-Fluoro-2-methylpropene (C4H7F) 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.

As a certified reference material (CRM), 3-Fluoro-2-methylpropene 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.
