112457-21-3 Usage
General Description
2,3,4-Pentanetrione, trioxime, (E,E)- is a chemical compound that is also known as parabenzoquinone trioxime. It is a yellow solid substance that is used in the synthesis of organic compounds. It is mainly used as a reagent in organic chemistry for the preparation of various heterocyclic and aryl compounds. It is also used as a catalyst in the synthesis of certain polymers and as a precursor in the production of pharmaceuticals and agrochemicals. It is important to handle this compound with care as it can be toxic if ingested or inhaled, and it may cause irritation to the skin and eyes upon contact.
Check Digit Verification of cas no
The CAS Registry Mumber 112457-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,4,5 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112457-21:
(8*1)+(7*1)+(6*2)+(5*4)+(4*5)+(3*7)+(2*2)+(1*1)=93
93 % 10 = 3
So 112457-21-3 is a valid CAS Registry Number.

The oximation of acetyl(hydroxyimino)aceton (1) with hydroxylamine affords a mixture of oxime derivatives.The products obtained by the action of an equimolar amount of hydroxylamine on (1) are the two 3,5-dimethyl-5-hydroxy-4-hydroxyimino-2-isoxazoline isomers (3a and b).The main products obtained by the action of an excess of hydroxylamine on (1) are two pentane-2,3,4-trione trioxime isomers (4a and b) and a little amount of 4-acetyl-3-methylfuroxan oxime (5).N.m.r. and chemical data of all these derivatives are discussed in order to determine both structures and configuration.X-Ray analysis of (3a), (4a), and (5) are also reported.
