The acid-base equilibria of a series of beta-adrenoceptor blocking drugs in acetonitrile have been studied, and pKHB+ values determined. The theory of such titrations is discussed and simple potentiometric and visual methods in acetonitrile media are proposed for the assay of beta-adrenoceptor block
The acid-base equilibria of 2-furoic acid hydrazide (FAH) and adipic acid dihydrazide (AADH) were investigated by pH measurements in water-dimethylformamide (10:60, v/v) and water-dioxane (10:60, v/v). The protonation constants were estimated by MINIQUAD which employs a non-linear least squares meth
The spectral behaviour of neutral molecules of acridine orange, 3,6diaminoacridine and rhodoamine B dissolved in ethanol has been studied. Contrary to previous conclusions, the neutral molecules do not dimerize in ethanol solutions. The spectral changes. thought to involve dimer-monomer systems, act
Isoprenoid polyphosphate intermediates of the mevalonate pathway were studied using 31P NMR. Acid-base titrations of farnesyl and geranylgeranyl polyphosphates were conducted over the pH range 4-10, and 31P chemical shifts were used to determine values for the second ionization step of the terminal
