This study introduces a series of novel Alkyl thio-1,2,4-triazole () and mercapto-1,2,4-triazole () compounds derived from nalidixic acid. The synthesis was streamlined, involving interactions between nalidixic acid hydrazide and various isothiocyanates to yield cyclic and alkyl(aryl) sulfide compounds, characterized using 1H NMR, 13C NMR, IR, and elemental analysis. Antioxidant capabilities were quantified through DPPH and ABTS assays, highlighting significant potential, especially for compound , which demonstrated an ABTS IC value of 0.

Green and sensitive spectrofluorometric methods have been developed and validated for the determination of timolol maleate (TML)/hydrochlorothiazide (HCT) and amiloride hydrochloride (AMH)/hydrochlorothiazide in tablets. The proposed spectrofluorometric procedures were found to be linear in the range of 4-12, 5-35 and 0.025-0.

Selectivity enhancement of membrane introduction mass spectrometry of nonpolar alkanes, alkenes, and aromatic hydrocarbons in air samples by application of nitric oxide chemical ionization (NOCI/MIMS) is demonstrated. Membrane methods are useful for separating compounds (usually nonpolar organics) from air and water samples without costly and time-consuming sample preparation, and coupled with mass spectrometry, they provide good sensitivity. But they often suffer from lack of specificity in mixture analysis, particularly for saturated organics.

A new method that we describe as chemical modulation of volatile hydrocarbons is investigated using ozonolysis pretreatment and membrane introduction mass spectrometry (MIMS). This extension to the MIMS technique is intended to enhance the selectivity of MIMS for measuring hydrocarbons in the complex mixtures often encountered in polluted air samples. The test samples for this study were dilute (parts per billion by volume, ppbv) two-component hydrocarbon mixtures in synthetic air.
