519-32-4 Usage
Description
ISOCAFFEINE is an impurity of Caffeine (C080100), a xanthine alkaloid that acts as a stimulant drug and a reversible acetylcholinesterase inhibitor. It is commonly found in pharmaceutical secondary standards for application in quality control, providing a convenient and cost-effective alternative to the preparation of in-house working standards.
Uses
Used in Pharmaceutical Industry:
ISOCAFFEINE is used as a secondary standard for quality control in pharmaceutical laboratories and manufacturers. It serves as a convenient and cost-effective alternative to the preparation of in-house working standards, ensuring the accuracy and reliability of pharmaceutical products containing caffeine.
Used in Research and Development:
ISOCAFFEINE is used as a research compound in the development of new drugs and therapies involving caffeine or its derivatives. Its presence as an impurity in caffeine allows researchers to study its effects and interactions with other compounds, potentially leading to the discovery of novel applications and treatments.
Used in Quality Control and Testing:
ISOCAFFEINE is used as a reference material in the quality control and testing of caffeine-containing products. It helps to ensure that the purity and concentration of caffeine in these products meet the required standards, maintaining the safety and efficacy of the final product for consumers.
Biochem/physiol Actions
1,3,9-Trimethylxanthine is an adenosine receptor antagonist.
Check Digit Verification of cas no
The CAS Registry Mumber 519-32-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 519-32:
(5*5)+(4*1)+(3*9)+(2*3)+(1*2)=64
64 % 10 = 4
So 519-32-4 is a valid CAS Registry Number.

Xanthinium N7-ylides were generated in situ from 7-substituted 9-methylxanthinium tosylates (2) using n-BuLi in tetrahydrofuran or Et3N in MeCN.The xanthinium N7-ylides (3) generated using Et3N in MeCN reacted with diphenylcyclopropenone to give pyrone derivatives and isocaffeine in good yields.The reactions of 3a-b with dimethyl acetylenedicarboxylate or methyl propiolate (MP) afforded 5-pyrrol-1-yluracils in moderate yields.N7-Methoxycarbonylmethylide (3c) reacted with MP to give a pyrrolopteridine derivative together with a 5-pyrrol-1-yluracil derivative.Furthermore, the dihydropyrrolopurine derivative (7) , a primary 1,3-dipolar cycloaddition product, was detected by nuclear magnetic resonance measurement of the products.Keywords - xantinium N7-ylide; cycloaddition; dimethyl acetylenedicarboxylate; methyl propiolate; diphenylcyclopropenone; 5-pyrrol-1-yluracil; pyrrolopteridine; isocaffeine
