Product Overview
Semaglutide is a synthetic analog of human glucagon-like peptide-1 (GLP-1) containing 31 amino acids with two key structural modifications: an aminoisobutyric acid (Aib) substitution at position 8 for DPP-4 resistance, and a C-18 fatty diacid chain linked to lysine-26 via a glutamic acid spacer. This design enables prolonged albumin binding and a half-life of approximately one week.
As a raw material supplier, we provide Semaglutide in its lyophilized powder form, suitable for downstream pharmaceutical manufacturing. Our API is produced via solid-phase peptide synthesis (SPPS) followed by preparative HPLC purification, controlled cleavage, and lyophilization to ensure batch-to-batch consistency.
This product is an active pharmaceutical ingredient (API) intended for use as a raw material in drug formulation. It is not a finished dosage form and is not intended for direct patient use.
Key Features
- High purity ≥98.5% by HPLC, with detailed impurity profiling
- Manufactured under cGMP in validated production facilities
- Consistent batch-to-batch quality with full traceability
- Lyophilized powder format for long-term stability
- Scalable supply from gram-level R&D to commercial bulk quantities
- Cold-chain logistics with real-time temperature monitoring
