Nicotinic acid complexes with uranyl salts

Transition Metal Chemistry, 1978
The potentially bidentate ligand, nicotinic acid, forms 2 : 1 complexes with uranyl chloride, sulphate, nitrate and acetate which have been characterized by i.r. spectral measurements down to 200 cm−1 in the solid state. These studies indicate conclusively that nicotinic acid coordinates onlyvia its pyridine ring nitrogen in all cases.

Thermal release of nicotine and its salts adsorbed on silica gel

Thermochimica Acta, 2017
Abstract Nicotine and its salts adsorbed on silica gel are employed to simulate the nicotine release behaviors of reconstituted tobacco particles (RTPs). Thermogravimetric analysis (TGA) was applied to provide an overview of the thermal behaviors of the nicotine, its salts and the RTPs.

Cellular effects of nicotine salt‐containing e‐liquids

Journal of Applied Toxicology, 2020
Abstract“Pod‐based” e‐cigarettes such as JUUL are currently the most prevalent electronic nicotine delivery systems (ENDS) in the United States. JUUL‐type ENDS utilize nicotine salts protonated with benzoic acid rather than freebase nicotine. However, limited information is available on the cellular effects of these products.

NICOTINE POISONING WITH A SALT OF NICOTINE

Journal of the American Medical Association, 1939
The reported instances of fatal nicotine poisoning according to Webster 1 and to Beeman and Hunter 2 are relatively infrequent. The nicotine insecticides are the usual preparations of nicotine used for suicidal purposes. To our knowledge there have been no reports of poisoning with a dry salt of nicotine.

The Form of Nicotine in Tobacco. Thermal Transfer of Nicotine and Nicotine Acid Salts to Nicotine in the Gas Phase

Journal of Agricultural and Food Chemistry, 1999
Thermal transfer to nicotine in the gas phase from neat nicotine, from various nicotine carboxylic acid salts, and from endogenous nicotine in Burley, Bright, and Oriental tobacco samples has been examined by thermogravimetric/differential thermal analysis/mass spectroscopy and evolved gas analysis.

Determining the solubilities for benzoate, nicotinate, hydrochloride, and malonate salts of bedaquiline

International Journal of Pharmaceutics, 2022
Determining the solubility of a compound is important for predicting its oral bioavailability, the medium to be used for dissolution, and solvents for cleaning during manufacturing. The solubilities of the newly synthesized benzoate, hydrochloride, nicotinate, and malonate salts of bedaquiline were elucidated, and the plausible reasons for the ...

Preparation and characterization of ambazone salt with nicotinic acid

AIP Conference Proceedings, 2012
Salt formation is a good method of increasing solubility, dissolution rate and consequently the bioavailability of poor soluble acidic or basic drugs. The aim of this study was to obtain and to investigate the structural properties of the compound that was obtained by solvent drop grinding method at room temperature starting from the 1:1 molar ratios ...

Remodeled salt appetite in rat offspring by perinatal exposure to nicotine

Appetite, 2009
To determine the effect of perinatal exposure to nicotine on water intake and salt appetite related to renin-angiotensin system in the offspring, maternal rats during perinatal period [gestation (G) or gestation plus lactation (G+L)] were subcutaneously administrated with nicotine.
