Chemical Structure
Description
7-Fluoro-3-(methoxymethoxy)-8-methylnaphthalen-1-yl trifluoromethanesulfonate (CAS 2791276-54-3), molecular formula C14H12F4O5S and molecular weight 368.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Fluoro-3-(methoxymethoxy)-8-methylnaphthalen-1-yl trifluoromethanesulfonate (C14H12F4O5S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 368.30 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
