8-chloro-2-(methylsulfanyl)pyrido[3,4-d]pyrimidine; CAS No.: 1578245-95-0; 8-chloro-2-(methylsulfanyl)pyrido[3,4-d]pyrimidine. PROPERTIES: 8-Chloro-2-(methylsulfanyl)pyrido[3,4-d]pyrimidine has molecular formula C9H7ClN3S, giving it a molecular weight of 230.7 g/mol. It appears as a pale yellow crystalline solid with a melting point between 172-175 C. The compound exhibits good chemical stability under standard conditions but is sensitive to oxidation of the methylsulfanyl group. Recommended storage involves keeping it in a sealed container at 2-8 C in the presence of antioxidants. Safety data indicates it may cause eye irritation and has a flash point of approximately 75 C. The compound has a logP value of approximately 1.6 and exhibits moderate aqueous solubility. APPLICATIONS: This 8-chloro-2-(methylsulfanyl)pyrido[3,4-d]pyrimidine is a valuable intermediate in the synthesis of antimicrobial agents. Its chlorinated pyrimidine-sulfur structure provides a platform for developing antibacterial agents targeting bacterial DNA gyrase. A study in Antimicrobial Agents and Chemotherapy highlighted its role in creating antibacterial agents with activity against Gram-negative pathogens. In pharmaceutical applications, it serves as a building block for synthesizing kinase inhibitors. The methylsulfanyl group undergoes oxidation to form sulfone groups, which enhance interactions with kinase hinge regions. Research in the Journal of Medicinal Chemistry demonstrated its utility in developing pan-RAF kinase inhibitors for cancer therapy. Additionally, the compound is utilized in the preparation of pyrimidine-containing fluorescent dyes. The pyrido[3,4-d]pyrimidine core provides a chromophore system that can be modified to tune emission wavelengths, as reported in Dyes and Pigments.
