553-17-3 Usage
Uses
Guaiacol Carbonate is used in method for preparing Polycarbonate Polyol and compound comprising the Polycarbonate Polyol.
Purification Methods
Crystallise the carbonate from EtOH. It is estimated by bromination to the monobromo guaiacol carbonate m 178o (from EtOH) [Chernoff J Am Chem Soc 51 3073 1929]. [Beilstein 6 H 776, 6 I 386, 6 II 784, 6 III 4233.]
Check Digit Verification of cas no
The CAS Registry Mumber 553-17-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 553-17:
(5*5)+(4*5)+(3*3)+(2*1)+(1*7)=63
63 % 10 = 3
So 553-17-3 is a valid CAS Registry Number.

, p. 105 - 109 (2007/10/03)
Treatment of difluorodiiodomethane with phenoxides (ArO-) in DMF at room temperature gives ArOCF2I in 7-15%, the carbonates (ArOCO2Ar) being the major products, while with thiophenoxides affords difluoromethylene derivativ
