Ethyl 4-amino-2-mercaptopyrimidine-5-carboxylate
Ethyl 4‑amino‑2‑mercaptopyrimidine‑5‑carboxylate is a heterocyclic ester employed as a building block in pharmaceutical and agrochemical synthesis. The molecule contains an amino group and a mercapto substituent on a pyrimidine ring, which makes it useful for constructing biologically active scaffolds. The supplier notes that the material is supplied with high purity and a stable shelf life suitable for research and manufacturing.
Typical physical data indicate a white to off‑white crystalline powder with a molecular weight around 226 g mol‑1. Purity of ≥ 98 % is common for research‑grade batches, as verified by HPLC. The compound is moderately soluble in polar organic solvents such as dimethylformamide and methanol, while showing limited solubility in water. Standard storage conditions are a cool, dry environment below 25 °C, and the material is classified as hazardous under GHS, with eye‑irritation and acute toxicity warnings.
It is widely purchased by medicinal chemistry teams, agrochemical developers and biotechnology laboratories for the synthesis of target molecules. The supplier advertises flexible minimum order quantities, allowing both small‑scale research orders and larger production runs. Prospective buyers should confirm the exact MOQ, preferred Incoterms such as FOB Shanghai or CIF destination, and the expected lead time with Shanghai Run‑Biotech Co., Ltd.
