What Rachael does

Selleck Chemicals LLC is a privately held U.S.-based supplier of research biochemicals and reagents, headquartered in Houston, Texas, with global operations spanning more than 20 countries through dedicated regional websites (including Korea, China, Japan, Australia, Germany, France, UK, and others). Founded in 2013, the company sells a catalog of small-molecule inhibitors, antibodies, proteins, kits, compound libraries, and bioreagents to academic, pharmaceutical, and biotechnology researchers worldwide. Its products are cited in Nature, Science, and Cell, and 17 Nobel Prize laureates have published 60 papers using Selleck reagents — a credential footprint that drives organic demand from the research community.

The core product platform is a 3,000+ SKU catalog organized by signaling pathway (PI3K/Akt/mTOR, JAK/STAT, MAPK, Epigenetics, Cell Cycle, DNA Damage/Repair, etc.), therapeutic area (multiple oncology indications plus diabetes, Alzheimer's, anti-aging), and product type (kinase inhibitors, molecular glues, PROTACs, ADC linkers, CFTR modulators, RNA methyltransferase inhibitors). Technical differentiators include high-purity products (97-99%+) with full Certificate of Analysis, NMR, and HPLC documentation; mutant-selective tool compounds such as Tersolisib (STX-478); pan-RAF-MEK molecular glues such as NST-628; and a comprehensive ADC linker portfolio for antibody-drug conjugate synthesis. All products are sold research-use-only.

Selleck operates a direct-to-consumer e-commerce model through country-specific storefronts with local language support, pay-as-you-go unit pricing, bulk-order availability, and temperature-controlled global shipping. Revenue derives from one-time catalog sales with no disclosed subscription or licensing component. The customer base is segmented horizontally across academic institutions, pharmaceutical/biotech companies, and disease-specific research programs. No external investors, funding rounds, or financial disclosures are present in the available data, and ownership is not publicly disclosed.

Direct peers

• AdooQ Bioscience: Niche research-use inhibitor and biochemical catalog serving academic and early-stage biotech discovery customers. Smaller and more specialty than Selleckchem but competes for the same catalog dollars with overlapping pathway coverage.
• MedChemExpress (MCE): China-headquartered catalog supplier of research-use biochemical inhibitors, modulators, and natural products serving the same academic and pharma discovery customers as Selleckchem. Often cited as the largest direct competitor on SKU breadth and pricing.
• Cell Signaling Technology (CST): Specialty antibody and reagent supplier focused on cell signaling, with adjacent kinase-inhibitor offerings for translational research. Overlaps with Selleckchem in pathway-targeted research reagents and the same PI3K/MAPK/JAK pathway biology.
• Enzo Life Sciences: Research reagents and assay kits supplier covering biochemicals, antibodies, and small-molecule tools. Comparable catalog model and academic/biotech customer base to Selleckchem.
• Tocris Bioscience: Established research-use biochemicals catalog (kinase inhibitors, ion channel tools, neurotransmitters) owned by Bio-Techne. Closest pure-play analog by catalog positioning, branding, and academic customer base.
• Cayman Chemical: Catalog supplier of research biochemicals, assay kits, antibodies, and natural products to academic and pharma researchers. Overlaps with Selleckchem on inhibitors, reference standards, and disease-area research reagents.
• Santa Cruz Biotechnology: Long-standing research-reagent catalog spanning antibodies, biochemicals, and labware to academic and biotech customers. Directly comparable in breadth, channel mix (catalog + online), and customer composition.

Broad incumbents

• Sigma-Aldrich (MilliporeSigma / Merck KGaA): Global incumbent for research chemicals, reagents, and analytical standards — including the Sigma-Aldrich and Supelco brands. Overlaps with Selleckchem on inhibitors, standards, and biochemicals but operates across a far broader portfolio.
• Bio-Techne: Public life-sciences tools holding company owning Tocris, R&D Systems, ProteinSimple, and other research-reagent brands. Comparable through its Tocris subsidiary and an indication of the strategic exit path for specialty catalogs like Selleckchem.
• Abcam: Research antibody specialist serving academic and pharma researchers globally. Adjacent to Selleckchem on the antibody category and overlapping customer pool, but with negligible small-molecule inhibitor catalog.
