Chemical Structure
Description
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.
4-Allyl-2-butoxy-1-fluorobenzene (CAS 1443311-69-0), molecular formula C13H17FO and molecular weight 208.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Allyl-2-butoxy-1-fluorobenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
