32685-16-8 Usage
General Description
Benzohydroxamic acid potassium salt, also known as potassium benzohydroxamate, is a chemical compound often used as a chelating agent in metal extraction and separation processes. It is a white, crystalline powder that is soluble in water and has a wide range of applications in various industries, including mining and metallurgy. As a chelating agent, it forms stable complexes with metal ions, making it useful in the recovery of valuable metals from ores and industrial waste. Additionally, it is also used in the production of pharmaceuticals and as an intermediate in organic synthesis. Despite its usefulness, benzohydroxamic acid potassium salt should be handled with care due to its potential irritant and harmful effects if not properly managed.
Check Digit Verification of cas no
The CAS Registry Mumber 32685-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,6,8 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 32685-16:
(7*3)+(6*2)+(5*6)+(4*8)+(3*5)+(2*1)+(1*6)=118
118 % 10 = 8
So 32685-16-8 is a valid CAS Registry Number.

In the present investigation, 6 compounds (E1-E6) were synthesized by reaction of ethyl esters of p-substituted benzoic acid with hydroxylamine. The chemical structures of the synthesized hydroxamic acids were verified on the basis of spectral analysis (IR, 1H NMR, 13C NMR and mass spectra). The benzohydroxamic acids were examined for potential local anesthetic activity using foot withdrawal reflex of the frog and benzocaine was used as standard drug. Compounds were tested at two different solvents; 5 % DMSO and 0.65 % NaOH, each solution was tested at three different concentration levels (40, 100 and 200 μg/mL). Local anesthetic activity of the compounds differed according to the concentration level and selected solvent. Compounds E4 and E5 were found to be the most active and were comparable to the standard drug in tested solvents at all investigated concentrations. All compounds displayed an enhanced activity in the the aqueous basic solutions.
