Abstract This study focuses on the synthesis of 2-[2 \ -(5-bromo thiazolyl) azo]-5-di-methyl amino benzoic acid (5-BrTAMB) and Cd(II) coordinate complex. Diazotization by 2-amino-5-bromo thiazole mixation an alkaline alcohol solution 3-dimethyl acid. Various analytical techniques, including 1 H-NMR, mass spectral, FT-IR spectra, UV-Vis, elemental analysis (C.H.N.S), measurement electrical condu...

Micellar solubilization is a powerful alternative for dissolving hydrophobic compounds in aqueous environment. Fluorescence and absorption spectroscopy are the two techniques used to monitor the micellar solubilization studies of p-amino benzoic acid (PABA). PABA is an aromatic compound with acidic functional group, is non essential nutrient, used as a sunscreen. Externally, it prevents sunburn...

In the title co-crystal, C(16)H(14)N(4)O(2)·2C(7)H(6)O(2), the 3,4-bis-[(pyridin-3-ylmeth-yl)amino]-cyclo-but-3-ene-1,2-dione squareamide mol-ecules assemble into chains along the b axis via N-H⋯O hydrogen bonds. The benzoic acid mol-ecules then hydrogen bond to the pyridine rings via O-H⋯N hydrogen bonds, supported by weaker C-H⋯O hydrogen bonds, forming extended ribbons. The asymmetric unit c...

A strain of Klebsiella aerogenes is described which was unable to grow from light inocula on 5% lysed horse blood diagnostic sensitivity test (DST) agar. It was able to grow on DST agar without added horse cells and MacConkey and nutrient agar. Growth on a deficient medium was promoted by sulphonamides and nitrofurantoin as well as by para-amino benzoic acid, para-amino salicylic acid, procaine...

para-aminobenzoic acid is supported on silica gel via reaction of activated silica gel and p-aminobenzoic acid which is then converted to its manganese and cobalt salts. a mixture of the manganese and cobalt salts of the acid is used to catalyze allylic and benzylic alcohols to their corresponding carbonyl compounds in reasonable yields using oxygen or air. reactions are clean and the catalysts...

In the title adduct, C(5)H(5)BrN(2)·C(7)H(6)O(2), the carboxyl group of the benzoic acid mol-ecule is twisted away from the attached ring by 12.97 (11)°. The 2-amino-5-bromo-pyridine mol-ecules inter-act with the carboxylic group of neighbouring benzoic acid mol-ecules through N-H⋯O and O-H⋯N hydrogen bonds, forming cyclic R(2) (2)(8) hydrogen-bonded motifs and linking the mol-ecules into a two...
