Conclusion: A simple, cost-effective, and sensitive spectrofluorimetric method was developed and validated for the determination of TOL in human plasma and pharmaceutical preparations using dansyl chloride.
An aliquot of 1 mL of the final extract was then derivatized by adding 200 [micro]L of NaOH 2 M, 300 [micro]L of saturated NaHC[O.sub.3] solution, and 2 mL of dansyl chloride solution (10 mg/mL in acetone).
The metabolites were identified based on retention time and accurate mass matching to a dansyl standard library or accurate mass matching to the human metabolome database (HMDB).
The samples were alkalized with KHC[O.sub.3] solution (pH 9.8), mixed with methanol, derivatized with dansyl chloride in the dark, and incubated at 80[degrees]C for 20 minutes, and 10 [micro]l acetic acid was added to stop the reaction.

Aminotroponiminates (H [sup.R]RATIs) with a dansyl fluorophore serve as a fluorescent NO biosensor, and paramagnetic [Co.sup.2+] complexes quench the fluorescence.
After incubating for 20 min at room temperature, dansyl chloride was added, and samples were incubated at room temperature in the dark for 24 hr.
A 200-[micro]L aliquot of each extract was added to 200 [micro]L of saturated [Na.sup.+], CO and 400 [micro]L of dansyl chloride (5 mg per mL of acetone) at room temperature, and mixed for 90 min at 70 [degrees]C in the dark.
