Chemical Structure
Description
CATO supplies (E)-3-Fluoro-2-methylacrylic acid (CAS 106910-18-3), a certified reference material (molecular formula C4H5FO2, MW 104.08 g/mol) for analytical method development and quality control.
Structurally, (E)-3-Fluoro-2-methylacrylic acid (C4H5FO2) 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 104.08 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.
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.
