Molecular Weight 4,113.64 g/mol
Purity ≥ 98.5% (HPLC)

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

Applications

Semaglutide API from our facility is used across a range of pharmaceutical development programs:

Injectable Formulations

Subcutaneous injection products designed for once-weekly dosing. Compatible with prefilled syringe and pen device development workflows.

Oral Dosage Forms

For oral Semaglutide tablet development using permeation enhancer co-formulation technology. Our API particle characteristics are optimized for oral processing.

Generic / ANDA Development

Reference-listed drug quality API for bioequivalence study programs. Supported by comparative analytical data and regulatory documentation.

Preclinical & Research

Research-grade supply available for mechanism-of-action studies, pharmacology research, and academic investigations into GLP-1 biology.
