J&W Pharmlab is a US-based contract research organization delivering custom molecule synthesis and medicinal chemistry support from our Pennsylvania laboratory. For over 24 years, we have been the trusted domestic chemistry partner for biotech companies, academic spin-outs, and federally funded research programs - trusted by teams at major pharma, NIH-funded academic labs, and Series A biotechs.

Whether you are managing an NIH DOD SBIR grants, running an AI-powered drug discovery platform, or advancing a lead compound to IND — we provide the synthesis expertise, communication, and compliance your project demands. We understand that SBIR/STTR programs operate within defined budgets, and we work closely with grantees to structure projects that deliver rigorous chemistry within those constraints.

Beyond custom synthesis, J&W Pharmlab has designed and produced over 30,000 novel building blocks for drug discovery R&D and medicinal chemistry applications. Our novel Fmoc-protected amino acid building blocks (partially shown below) deliver the structural diversity and high-coupling efficiency essential for advanced peptide libraries and specialized drug discovery. Our compounds have been adopted widely across the research community — with over 1,000 published drug discovery patents citing our products as key materials in their research programs. This track record reflects the quality, reliability, and scientific rigor that J&W Pharmlab brings to every project.

For AI-driven drug discovery programs, we accept structure submissions in SMILES, MOL, or SDF format, return synthetic feasibility assessments within 24 hours, and assign a PhD chemist as your direct scientific contact. Our 30,000+ novel building blocks expand the chemical space your AI can access in practice. All synthesis is performed at our Pennsylvania facility — no foreign subcontracting, and full compliance for NIH SBIR, STTR, and any government-funded programs. Unlike offshore alternatives, you always know who is handling your chemistry.

We deeply respect the confidentiality of your proprietary research and are happy to provide CDA/NDA templates to protect your intellectual property before any project discussions begin. Located in the heart of the East Coast pharma hub, we also welcome clients to visit our facility in person — a great opportunity to meet your dedicated PhD chemists, tour our labs, and build the kind of working relationship that keeps projects moving.
