Applications
2-Amino-5-chloropyridine is a common disubstituted pyridine heterocyclic intermediate with amino and chloro groups on the pyridine ring. It has high chemical reactivity and can participate in diazotization, nucleophilic substitution, Suzuki coupling, Buchwald amination and condensation reactions. It is widely used as key building block for antitumor, anti-inflammatory, antibacterial and central nervous system drug intermediates, kinase inhibitor fragments and targeted small molecule drug synthesis. It is also applied in medicinal chemistry structure-activity relationship research, custom fine chemical synthesis and new agrochemical fungicide and herbicide intermediate development.
Safety Information
Irritating to skin, eyes and respiratory tract. Inhalation of dust may cause throat discomfort, dry cough and respiratory mucosal irritation; direct eye contact leads to stinging, redness and conjunctival congestion. Prolonged skin contact may cause dryness and allergic irritation. Avoid dust inhalation, prolonged skin contact and eye exposure.
