1. 4-Bromo-3-methyl-1H-pyrazole may be used in chemical synthesis.
2. 4-Bromo-3-methylpyrazole is an intermdiate used to prepare substituted piperidines as potent, selective, CNS-penetrant α4β2 nicotinic acetylcholine receptor potentiators. It is also used to prepare small molecular B2 receptor antagonists.
Check Digit Verification of cas no
The CAS Registry Mumber 13808-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,0 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13808-64:
(7*1)+(6*3)+(5*8)+(4*0)+(3*8)+(2*6)+(1*4)=105
105 % 10 = 5
So 13808-64-5 is a valid CAS Registry Number.

Facile, fast and safe process development of nitration and bromination reactions using continuous flow reactors
Pelleter, Jacques,Renaud, Fabrice
, p. 698 - 705 (2009)
Chemists working in a pilot plant often face safety issues during scale-up operations. With the help of emerging microfluidic applications and microdevices, running hazardous, highly exothermic or potentially unstable reactions can be easily transposed into a safe continuous flow mode. This paper describes how a potentially hazardous pyrazole nitration and the bromination of a variety of electron-rich heteroaromatic substrates were efficiently performed using a cheap and easily available system for bench chemists. Advantages of the continuous flow mode in organic synthetic chemistry will be exemplified by the large-scale production of raw materials under safe, green and reproducible conditions.
