从China供应商批发进口2-Amino-6-Chloropurine — FOB条款

2-Amino-6-Chloropurine is a white to off-white powder used as a critical building block in nucleoside chemistry. Its key physical properties include a melting point of 300°C, a density of 2.09 g/cm³, and very low water solubility of 1.7 g/L at 20°C. The compound has a flash point of 144.4°C and a refractive index of 1.826, with a negligible vapor pressure of 1.75E-15 mmHg at 25°C.

This chlorinated purine derivative is a precursor for synthesizing guanine-based nucleosides and nucleotides, which are fundamental in antiviral and anticancer drug development. The material is classified under HS code 2933990090 and is considered harmful by inhalation, in contact with skin, and if swallowed (Risk Phrases R20/21/22). It requires storage under cold conditions to maintain stability and should be handled with standard precautions for irritant chemicals.

The primary buyers are pharmaceutical companies and research institutions involved in medicinal chemistry and nucleoside analog synthesis. Sourcing this intermediate from Hangzhou Shitai Biotech in Hangzhou, China, requires confirming the supplier's cold chain logistics capabilities and specific purity grades available. Importers should note the compound's irritant and harmful classifications (Hazard Codes Xi, Xn) and ensure proper safety documentation is in order for their jurisdiction.
