Chemical Structure
Description
Structurally, 1-(Difluoromethyl)-3,3-dimethoxycyclobutanecarboxylic acid (C8H12F2O4) 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 210.18 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-(Difluoromethyl)-3,3-dimethoxycyclobutanecarboxylic acid (CAS 2719726-03-9) is a high-purity analytical reference standard with the molecular formula C8H12F2O4 and a molecular weight of 210.18 g/mol.
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.
