The quinazoline scaffold is a privileged structure in medicinal chemistry, forming the backbone of numerous biologically active compounds, including many successful pharmaceuticals. Among these, 4-Chloro-6-iodoquinazoline (CAS 98556-31-1) stands out due to its critical role in the synthesis of Lapatinib, a targeted therapy for various cancers. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying this key intermediate, recognizing its importance in both established drug manufacturing and the broader landscape of drug discovery.

The quinazoline ring system itself is a fusion of a benzene ring and a pyrimidine ring. This bicyclic structure offers a versatile platform for modification, allowing chemists to introduce various substituents at different positions to fine-tune a molecule's biological activity, pharmacokinetic properties, and toxicity profile. The specific substitutions in 4-Chloro-6-iodoquinazoline – a chlorine atom at the 4-position and an iodine atom at the 6-position – are strategically important for its utility in synthesizing Lapatinib. These halogen atoms serve as reactive handles for further chemical transformations, such as nucleophilic aromatic substitution and cross-coupling reactions, which are fundamental to building the Lapatinib molecule.

The most prominent application of 4-Chloro-6-iodoquinazoline is its use as a precursor in the Lapatinib synthesis pathway. Lapatinib, a potent inhibitor of EGFR and HER2 kinases, has proven effective in treating certain types of advanced breast cancer. The synthesis of Lapatinib typically involves coupling reactions that utilize the reactive sites provided by the 4-chloro and 6-iodo groups of this intermediate. This makes 4-Chloro-6-iodoquinazoline an indispensable raw material for pharmaceutical companies specializing in oncology and targeted therapies.

The study of quinazoline derivatives extends beyond Lapatinib. The quinazoline core is found in drugs with various therapeutic applications, including anti-cancer agents, antihypertensives, and anti-inflammatory compounds. Researchers often utilize well-characterized intermediates like 4-Chloro-6-iodoquinazoline to explore new drug candidates. The availability of high-purity intermediates facilitates faster and more reliable drug discovery efforts, enabling the rapid testing of new chemical entities.
