Description
Ethyl 5-(formylamino)-1H-pyrazole-4-carboxylate, also known as 3-(Formylamino)-1H-pyrazole-4-carboxylic Acid Ethyl Ester, is an impurity of Allopurinol, a pyrazole derivative with potential applications in inducing neoplasm immunogenicity.
Uses
Used in Pharmaceutical Industry:
Ethyl 5-(formylamino)-1H-pyrazole-4-carboxylate is used as an impurity in Allopurinol, a medication primarily used for the treatment of gout and hyperuricemia. Its presence in Allopurinol may contribute to the drug's therapeutic effects or require monitoring and control to ensure safety and efficacy.
Check Digit Verification of cas no
The CAS Registry Mumber 31055-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,5 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31055-19:
(7*3)+(6*1)+(5*0)+(4*5)+(3*5)+(2*1)+(1*9)=73
73 % 10 = 3
So 31055-19-3 is a valid CAS Registry Number.

Reactions between aminopyrazole-4-carboxylic acids derivatives and orthoesters or amide acetals lead, in most cases, to the introduction of a heteroalkylidene moiety on the amino group of ethyl aminopyrazole-4-carboxylates and on the β-hydrazide nitrogen atom of aminopyrazole-4-carboxhydrazides. Several factors governing the course of these reactions are discussed.
