CAS 24994-04-5 — 5-(4-Methylphenyl)tetrazole

5-(4-Methylphenyl)tetrazole is a high-purity heterocyclic compound widely used as a key intermediate in pharmaceutical synthesis, particularly for the production of angiotensin II receptor antagonists like losartan. It serves as a critical building block in drug development due to its unique tetrazole ring structure, which enhances biological activity. This chemical has a CAS number of 24994-04-5, a molecular formula of C8H9N4 (not C14H14O3, which appears to be incorrect), and a molecular weight of 161.19 g/mol. It is stable at ambient storage conditions and carries no signal word for hazard classification. Molekula supplies 5-(4-Methylphenyl)tetrazole from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
