In the cation of the title co-crystal salt {systematic name: [2-hydroxy-2-(3-meth-oxy-phen-yl)cyclo-hexyl-meth-yl]dimethyl-aza-nium chloride-benzoic acid (1/1)}, C(16)H(31)NO(2) (+)·Cl(-)·C(7)H(6)O(2), the N atom is protonated and the six-membered cyclo-hexane ring adopts a slightly distorted chair conformation. The dihedral angle between the mean planes of the benzene rings in the cation and t...
A 4-aza-1-azoniabicyclo-[2.2.2]octane cation, a 2-amino-benzoate anion and a neutral 2-amino-benzoic acid mol-ecule comprise the asymmetric unit of the title compound, C(6)H(13)N(2) (+)·C(7)H(6)NO(2) (-)·C(7)H(7)NO(2). An intra-molecular N-H⋯O hydrogen bond occurs in the anion and in the neutral 2-amino-benzoic acid mol-ecule. The cation provides a charge-assisted N-H⋯O hydrogen bond to the ani...
Cr(III), Co(II), Ni(II), Cu(II) and Zn(II) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their in-vitro antimicrobial activity against three bacterial strains, Mycobacterium smegmatis (Gram +ve), Escherichia coli (Gram -ve), Pseudomonas aeuroginosa (Gram -ve) and three fungal strains, Nigrospora oryzae, A...
Fourteen aromatic and 24 aliphatic acids were determined by GC-MS analysis of acidic fractions obtained from Paeonia peregrina and Paeonia tenuifolia roots. Benzoic acid and its monohydroxy-, dihydroxy- and trihydroxy-derivatives are the main acid components of both Paeonia species. Some fractions could serve as a source of benzoic, 4-hydroxybenzoic, vanillic and gallic acids, as well as of eth...
Emission of methyl benzoate, one of the most abundant scent compounds of bee-pollinated snapdragon flowers, occurs in a rhythmic manner, with maximum emission during the day, and coincides with the foraging activity of bumblebees. Rhythmic emission of methyl benzoate displays a "free-running" cycle in the absence of environmental cues (in continuous dark or continuous light), indicating the cir...
Abstract In this work, we used the design strategy “doped nonpolar polymers” and synthesized polyurethane elastomers (PUEs) by doping with highly polar aromatic molecules such as benzoic acid (BA), 4(para)-nitro-benzoic (PNBA), 3, 5-di-nitro-benzoic (3, 5-DNBA) using solution casting method. The effect of each molecule in three different weight percentages 2%, 4%, 6% on electrical thermo-mechan...
