110-20-3 Usage
Description
Acetone semicarbazone is an organic compound derived from the reaction between acetone and semicarbazide. It is a white crystalline solid with a chemical structure that allows it to be used as a precursor in the synthesis of various compounds.
Uses
Used in Pesticide Industry:
Acetone semicarbazone is used as a starting material for the synthesis of Isazophos, which is a pesticide. It serves as a key intermediate in the production process, contributing to the development of Isazophos and its application in agriculture for pest control.
Safety Profile
Poison by intravenous route. Whenheated to decomposition it emits toxic fumes of NOx.
Purification Methods
Acetone semicarbazone crystallises from water or from aqueous EtOH. [Beilstein 3 H 101, 3 I 48, 3 II 81, 3 III 189, 3 IV 179.]
Check Digit Verification of cas no
The CAS Registry Mumber 110-20-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 110-20:
(5*1)+(4*1)+(3*0)+(2*2)+(1*0)=13
13 % 10 = 3
So 110-20-3 is a valid CAS Registry Number.

Cyclization of the semicarbazones to 1,3,4-oxadiazole derivatives using ceric ammonium nitrate as oxidant

experimental part, p. 288 - 290 (2012/08/08)
Cyclization of the semicarbazones to 1,3,4-oxadiazole using ceric ammonium nitrate as oxidant was studied. 2-Imino-1,3,4-oxadiazolines can be produced from semicarbazones, which undergo thermolysis to amides. Benzoic acid benzylidene hydrazide can also be cyclized to 2-methoxy-2-phenyl-1,3,4-oxadiazole in the presence of ceric ammonium nitrate and methanol.
