used solvents include alcohol, tetrahydrofuran, DMF, and water. It generally does not reduce an ester group, a carboxyl group, and amide. However, when combined with appropriate solvent or catalyzed by Lewis acid in high temperature, it can be used for reducing weak carbonyl group such as ...
Compared with the standard heparin, low molecular weight heparin has a strong role of anti-clotting factor X but has a very weak role of anticoagulant II factor and inhibiting the action of thrombin. Thereby this product has a strong antithrombotic effect with less bleeding complications. In ...
In general, 23Na NMR can provide important petrophysical information, such as monitoring changes in ionic strength of brine during water-flooding of a reservoir, or detecting water-based mud (WBM) filtrate invasion into the near-well-bore formation when sodium formate or bromide are used as ...
(1996), incorporated two amphiphilic drugs: propantheline bromide and oxybutynin HCl in this system, and proposed their partition mostly at the lipid–water interface. Both drugs investigated promoted the formation of the lamellar phase and showed the sustained release over a period of 18 and 20 ...
Ammonium copper(I), cadmium and nickel halides generally gave weak explosions, and most of the alkali- and alkaline earth-metals were insensitive.A mixture of sodium and chromium tetrachloride creates a very violent explosion on impact.Silver bromide, silver chloride, silver fluoride, and silver ...
However, secondary haloalkanes tend to react with strong nucleophiles that are weak bases, such as thiolates or cyanide ion, by an SN2 process. Sign in to download full-size image On the other hand, a secondary haloalkane tends to react with weak nucleophiles that are also weak bases, ...

Allhalides, except fluoride, interfere in the determination of silver. An approximately equimolar amount of chloride can be tolerated. In certain cases, large amounts of chloride or bromide may be used to mask silver in the determination of other noble metals with TMK.Thiosulphate,thiocyanate, sulp...
These cations include metal cations: Ca2 +, Na +, K +, long-chain pyridine compounds of organic base such as cetyl pyridinium chloride (CPC), strychnine, basic dyes-Azure A, cationic surfactants ( long chain quaternary ammonium salts) such as cetyl trimethyl ammonium bromide; cation exchanger ...
