POLYPEPTIDE LABORATORIES SAN DIEGO, LLC

Polypeptide Laboratories San Diego, LLC specializes in the synthesis, characterization, and distribution of complex peptide-based drug substances, with deep expertise in opioid and related analogs for federal research and regulatory applications. The contractor provides end-to-end chemistry, manufacturing, and control (CMC) services, including analytical method development, stability testing, and storage studies for drug substances under strict GMP-aligned protocols. Their technical capabilities span organic synthesis of controlled substances, pharmaceutical formulation support, and rigorous quality assurance for research-grade materials used in preclinical and clinical development. A key differentiator is their sustained focus on high-purity peptide production under controlled substance regulations, enabling reliable supply chains for sensitive federal research programs. The company maintains a long-standing, recurring relationship with the Department of Health and Human Services, particularly through NIH components such as NICHD and NIDA, delivering specialized chemistry and testing services critical to opioid research, drug stability evaluation, and substance control initiatives. Their work supports mission-critical federal efforts in pain management, addiction science, and pharmacological standards development, with contracts spanning over a decade demonstrating consistent performance and regulatory compliance. Primary industry focus lies in research and development within the physical and life sciences, alongside testing laboratories and medicinal manufacturing. This positions them as a niche provider of peptide-based CMC solutions for government-funded biomedical research, bridging synthetic chemistry with regulatory-grade production. Their work supports the development of reference standards, analytical controls, and investigational compounds used in federal drug policy and therapeutic innovation. As a limited liability company based in San Diego, California, Polypeptide Laboratories operates as a specialized technical service provider without federal certifications. Their geographic presence and technical focus make them a trusted, low-profile partner for sensitive government research programs requiring precision chemistry and controlled substance handling capabilities.
