595-30-2 Usage
Chemical Properties
white fine crystalline powder
Uses
(+/-)-Camphoric anhydride is useful in the synthesis of aliphatic-aromatic copolyesters. It is also used as pharmaceutical intermediates.
Purification Methods
Crystallise the anhydride from EtOH. If it contains too much of the acid (by IR), then reflux it in Ac2O, concentrate and collect the crystals, wash them with pet ether and dry them. [Bunton et al J Chem Soc 2918 1963, NMR: Baker & Davis Tetrahedron 24 1663 1968, Beilstein 18 H 400, 401.]
Check Digit Verification of cas no
The CAS Registry Mumber 595-30-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 595-30:
(5*5)+(4*9)+(3*5)+(2*3)+(1*0)=82
82 % 10 = 2
So 595-30-2 is a valid CAS Registry Number.

PHOTOSENSITIZED OXYGENATION OF 3-DIAZOCAMPHOR
Okada, Keiji,Mukai, Toshio
, p. 359 - 360 (2007/10/02)
Photosensitized oxygenation of 3-diazocamphor gave camphorquinone and camphoric anhydride in benzene.The yield of camphoric anhydride did not depend on the concentration of added camphorquinone or of diazocamphor.When the reaction was carried out in acetonitrile or benzonitrile, amide 7 or 8 was produced.The formation of amide strongly supports the intermediacy of carbonyl oxide.
