110-20-3 Usage
Uses
Acetone Semicarbazone is used as the starting material to synthesize Isazophos which is a pesticide.
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.
