The global Peptide Thioester market size is predicted to grow from US$ 149 million in 2025 to US$ 274 million in 2032; it is expected to grow at a CAGR of 9.2% from 2026 to 2032.

Peptide thioesters are peptide chains whose C-terminus is converted into a thioester functional group (?COSR), enabling chemoselective ligation reactions such as native chemical ligation (NCL) for synthesizing large, complex, or post-translationally modified proteins. Their supply chain begins with protected amino acids and specialized coupling reagents used in solid-phase peptide synthesis (SPPS), followed by thioester-generating strategies such as safety-catch linkers (e.g., sulfonamide, hydrazide, SEA linkers), thiol-resin supports, or enzymatic/thioacid-based routes. After synthesis, purification is performed through preparative HPLC, lyophilization, and stringent QC for purity, sequence fidelity, and thioester stability. Downstream, peptide thioesters move through specialty peptide manufacturers, biochemical suppliers, and custom synthesis firms to research labs, pharmaceutical companies, and biotech groups developing synthetic proteins, peptide therapeutics, biomaterials, and semisynthetic enzymes. In 2025, global peptide thioester production reached approximately 138,000 kilograms, supported by a total installed capacity of around 160,000 kilograms annually. Average market pricing ranges from USD 850 to 1,500 per kilogram, and the sector maintains a strong 47% gross margin.
