It is particularly effective against infections caused by Trichomonas, Giardia, and other pathogens.

Check Digit Verification of cas no

The CAS Registry Mumber 25459-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,5 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25459-12:
(7*2)+(6*5)+(5*4)+(4*5)+(3*9)+(2*1)+(1*2)=115
115 % 10 = 5
So 25459-12-5 is a valid CAS Registry Number.

Potassium fluoride on alumina - An efficient reagent for isomerization of N-[2-(Alkyl/Arylsulfonyl)ethyl]-2-methyl-5-nitro-1H-imidazoles

Bhujanga Rao,Gundu Rao,Singh

, p. 443 - 448 (2007/10/02)

KF/Al2O3 has been found to be an efficient reagent for a neat isomerization of 1-[2-(Alkyl/Arylsulphonyl)ethyl]-2-methyl-5-nitro-1H-imidazoles to the corresponding 4-nitro-isomers in more than 90% yields.

Isomerization of Tinidazole involving a Novel N-Alkyl Group Migration

Rao, A. K. S. Bhujanga,Prasad, Ramanujam S.,Rao, C. Gundu,Singh, Bajrang B.

, p. 1352 - 1353 (2007/10/02)

Tinidazole undergoes base-catalysed N-alkyl group migration in almost quantitative yields to give its 4-nitro isomer, an observation which may lead to a better understanding of the metabolism of this drug.
