  PE 22-28 High Purity API Intermediate (CAS: 1801959-12-5) is a key heterocyclic synthetic intermediate dedicated to laboratory pharmaceutical synthesis research. The product adopts full-enclosed low-temperature synthesis, multi-stage recrystallization purification and vacuum drying process, effectively removing residual catalysts, unreacted raw materials and heavy metal impurities. The finished product presents uniform white crystalline solid, with HPLC single-point purity ≥99%, each single unknown impurity less than 0.1%, total impurities controlled below 1.0%. The whole production line follows laboratory chemical raw material quality control standards, strictly limits heavy metal, microbial and endotoxin residues, greatly reducing interference in subsequent synthetic route trials and ensuring stable yield and repeatability of multi-step API synthesis experiments. Its unique heterocyclic molecular skeleton can participate in multiple coupling and cyclization reactions, widely applied in novel small-molecule drug route exploration, pharmaceutical process optimization, intermediate structure modification and compound library construction for academic research labs and pharmaceutical R&D institutions.
