7529-17-1 Usage
General Description
Pyrrolidine, 1-methyl-, 1-oxide, also known as N-methylpyrrolidone (NMP), is a chemical compound with the molecular formula C5H9NO. It is a clear, colorless liquid with a faint amine odor. NMP is commonly used as a solvent in various industrial and pharmaceutical applications, such as in the production of polymers, resins, and pharmaceutical drugs. It is also used in the electronics industry for the cleaning and degreasing of electronic components. NMP is valued for its high solvency and low volatility, making it an effective and efficient solvent for a wide range of applications. However, it is important to handle NMP with caution, as it can be harmful if inhaled, absorbed through the skin, or ingested.
Check Digit Verification of cas no
The CAS Registry Mumber 7529-17-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,2 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7529-17:
(6*7)+(5*5)+(4*2)+(3*9)+(2*1)+(1*7)=111
111 % 10 = 1
So 7529-17-1 is a valid CAS Registry Number.

Amine Autoxidation in Aqueous Solution
Beckwith, Athelstan L. J.,Eichinger, Peter H.,Mooney, Brett A.,Prager, Rolf H.
, p. 719 - 739 (2007/10/02)
The uncatalysed autoxidation of aqueous of tertiary aliphatic amineshas been studied in order to obtain information concerning the mechanism of oxidation of Sirotherm resins.Oxidation occurs most rapidly in the free base, and the general correlation of rate with pKa or ionization potential suggests that electron transfer to form an aminium radical cation is rate-determining.The reaction is not initiated by free radical initiators, nor inhibited by radical traps.It is significantly catalysed by strong electron acceptors and by light and is moderately inhibited by the electron donor N-phenylanthranilic acid.Pyrrolidines and hexahydroazepines are oxidized faster than piperidines, and hydroxyl groups on β-carbons increase the rate of oxidation, while those on γ-carbons decrease it.The major products of autoxidation of alkyl pyrrolidines in water were found to be N-oxides.Various pyrrolidinones were isolated in smaller yield.
