Peptide Synthesis
The peptide therapeutics market is rapidly expanding across oncology, metabolic disorders, rare diseases, and neurodegenerative conditions. SK pharmteco is expanding its capabilities to support custom synthetic peptide APIs and protected amino acids from early clinical development to commercial scale, delivering reliable supply with quality you can trust.
Peptide Capabilities
Peptides
Our developing offering includes scalable peptide solutions using SPPS, LPPS, and hybrid approaches – ensuring robust processes,
cost efficiency, and supply continuity.
Chromatography Expertise
We deliver high-purity peptides using reverse-phase batch chromatography operated in isocratic or gradient modes, as well as continuous twin-column technology such as MCSGP.
Integrated Analytical Testing
From method development to commercial release testing, our
in-house analytical services are integrated with production to streamline tech transfers and accelerate timelines.


IND-Enabling Preclinical Development Services
SK pharmteco’s IND-enabling preclinical package delivers end-to-end support for preclinical gene therapy studies and includes access to a proprietary manufacturing cell line, streamlined process development services, and scalable preclinical vector manufacturing services, as well as regulatory support for INitial Targeted Engagement for Regulatory Advice on CBER/CDER ProducTs (INTERACT) and pre-IND meetings.
This package:
- Enables partners to generate high-quality material and data in months and positions them to move rapidly toward IND approval and CGMP clinical manufacturing
- Supplies drug substance and drug product for proof-of-concept, toxicology, safety, and biodistribution studies, as well as method development, interim reference standards, development stability, and drug product development critical for IND packages
- Employs similar processing techniques as would be used for full CGMP manufacturing, eliminating comparability risks associated with process changes
Additional analytical testing and regulatory services are available to prepare data briefing packages for INTERACT and pre-IND meetings. Upon completion of preclinical manufacturing, clients have full visibility into the data from execution, production, and purification — a critical data set for clinical program sponsors.

Peptide FAQs
A peptide CDMO is a Contract Development and Manufacturing Organization that provides development, scale-up, and manufacturing services for peptide therapeutics. These organizations support pharmaceutical and biotech companies by delivering custom peptide synthesis, process development, purification, and analytical testing to advance programs from clinical development to commercial production.
Peptide synthesis services support process development, analytical development & characterization, and scale-up & manufacturing of synthetic peptides used as therapeutic drugs.
Custom peptide synthesis services typically use solid-phase peptide synthesis (SPPS), liquid-phase peptide synthesis (LPPS), or hybrid approaches that combine both technologies. SPPS is often used for rapid early-stage peptide development, while LPPS and hybrid synthesis strategies are more flexible for scale-up as the process advances to larger-scale and commercial production.
A peptide CDMO supports scale-up by developing robust synthesis and purification processes that maintain yield, purity, and reproducibility as production volumes increase.
Chromatography is critical for achieving the purity required for therapeutic peptides. Advanced purification methods such as reverse-phase chromatography and twin-column systems enable efficient downstream processing, helping manufacturers achieve high yield and purity across different scales of peptide production.
Peptides require extensive analytical testing to confirm identity, purity, potency, and stability. Integrated analytical services support method development, validation, and release testing to ensure regulatory compliance and consistent product quality throughout development and commercial production.
Peptide manufacturing can be complex due to scale-up challenges, purification requirements, and regulatory expectations. Achieving high purity and yield often requires specialized chromatography capabilities and integrated analytical testing to prevent bottlenecks and ensure reliable supply.
Yes. Many peptide CDMOs provide scalable development and manufacturing services that support programs from early clinical stages through commercial production. Integrated capabilities in synthesis, purification, and analytical testing help streamline technology transfer and accelerate development timelines.
