Alkali Scientific Allopurinol [4 Hydroxypyrazolo [3,4 d]pyrimidine], 150 G
Allopurinol is a well known xanthine oxidase inhibitor used in laboratory research to study purine metabolism and enzyme inhibition mechanisms. By blocking the conversion of hypoxanthine and xanthine into uric acid, it helps researchers analyze metabolic pathways and oxidative processes in biological systems. This compound is frequently used in biochemical assays, pharmacological research, and experimental models related to uric acid regulation and metabolic disorders. Its consistent inhibitory action makes it valuable for studying enzyme kinetics and drug interactions. Supplied in a 150 gram quantity, it is ideal for high volume laboratory applications and large scale experimental preparation.
