Frequently Asked Questions (Research Context Only)

Q: What solvents are recommended for preparing 4-FA stock solutions for HPLC analysis?
A: Methanol, acetonitrile, or deionized water (HPLC grade) at 1 mg/mL concentration. For GC/MS, derivatization with MSTFA or similar agents is recommended for optimal volatility.

Q: How stable is 4-FA in solution compared to the solid powder form?
A: Solid powder is stable for 24 months at room temperature. In methanol solution at -20°C in amber vials, 4-FA shows <3% degradation over 6 months. Prepare fresh working standards daily.

Q: What is the recommended LC-MS/MS ionization mode for 4-FA quantification?
A: Positive ion mode electrospray ionization (ESI+) yields optimal protonated molecular ion [M+H]+ at m/z 154.1. Multiple reaction monitoring (MRM) transitions are available on the CoA.
