Application
7-Bromo-2,4-diaminoquinazoline (CAS 137553-43-6) is a functionalized quinazoline derivative bearing two amino groups at the 2- and 4-positions and a bromine at the 7-position. This privileged heterocyclic scaffold is widely used in medicinal chemistry for the synthesis of potent tyrosine kinase inhibitors, particularly targeting EGFR, HER2, and VEGFR in non‑small cell lung cancer, breast cancer, and other solid tumors. The bromine enables cross‑coupling reactions (Suzuki, Buchwald‑Hartwig) for late‑stage diversification, while the 2,4‑diamino motif allows additional amide or urea formation. This building block is also utilized in developing antiviral, anti‑inflammatory, and antimicrobial agents. High purity ensures reproducible results in high‑throughput screening, SAR studies, and scalable GMP synthesis.
