Aloe-emodin Acetyl-Hexapeptide-38-supplier Apelin-15-(63-77)-peptide (Tyr0)-Fibrinopeptide-A
1. Early‑Stage Drug Discovery – A US biotech used 5 kg of C20‑Otbu‑glu‑otbu to synthesize a novel GLP‑1 analog. The high purity reduced downstream purification steps, cutting the total synthesis cost by 28 % and accelerating IND filing by 45 days.
2. Large‑Scale Manufacturing – An established pharma partner ordered 2 tons for a Phase III trial. Our high‑speed logistics delivered the full consignment within 6 days, preventing a projected 3‑week production halt.
3. Custom Salt Form Development – Through our OEM service, a CRO obtained a calcium salt of C20‑Otbu‑glu‑otbu, improving aqueous solubility by 3.8‑fold, which directly translated into a lower dose requirement.
