●Amino Acids

Iris Biotech offers a diverse portfolio of amino acid derivatives for peptide and life science research, along with tailored solutions to support specific R&D requirements. These products are designed to meet the needs of modern peptide synthesis, modification, and related discovery workflows. 

●Building Blocks

Iris Biotech’s specialized building blocks support the synthesis of complex peptides, peptidomimetics, modified peptide structures, peptide nucleic acids, and other oligonucleotides such as DNA, RNA, and LNA. The portfolio includes pseudoproline dipeptides based on cysteine, serine, and threonine, isoacyl dipeptides for improved synthetic efficiency, as well as spermines, spermidines, hydrazines, linear and cyclic diamines, amino alcohols, amino aldehydes, and fatty acid derivatives with different protecting group options. 

●Drug Delivery

Iris Biotech offers a broad library of polymer carriers for advanced drug delivery applications. In addition to PEGylation tools, the portfolio includes biodegradable polyamino acids, poly(2-oxazoline)s for tunable hydrophobicity and surface properties, and other materials such as functionalized fullerenes, fullerols, dextrans, plant-derived cholesterol, and nanoparticles, providing researchers with flexible options for polymer therapeutics and delivery strategy development. 

●Click Chemistry

Iris Biotech provides reagents for all major generations of click chemistry. Its portfolio covers first-generation Cu(I)-catalyzed azide–alkyne cycloaddition for efficient formation of 1,4-disubstituted triazoles, as well as copper-free alternatives including strain-promoted azide–alkyne cycloaddition and tetrazine ligation for fast, bioorthogonal reactions in sensitive biomolecular and in vivo applications. 

●Linkerology®

Under its Linkerology® platform, Iris Biotech offers a wide range of linker solutions for solid-phase chemistry, bioconjugation, antibody-drug conjugates, and related applications. The portfolio includes linkers with multiple functional groups and can also be adapted through custom design to meet specific project requirements. 

●Life Sciences

The life sciences portfolio includes biotinylation reagents, carbohydrates, metabolites, substrates, inhibitors, dyes, fluorescent labels, Maillard reaction products, biologically active peptides, vitamins, and natural products. These materials are intended to support a broad range of biochemical, analytical, and cell-based research applications. 

●Reagents

Iris Biotech supplies a selected range of standard and specialty reagents for solid-phase chemistry, including coupling reagents, solvents, scavengers, protecting-group reagents, and other useful synthesis tools. These products are designed to support efficient and practical peptide and organic synthesis workflows. 

●Resins

Iris Biotech offers a broad resin portfolio ranging from hydrophobic polystyrene-based polymers to more hydrophilic supports for different application conditions. These resins can be used in solid-phase synthesis as well as immobilized scavengers for removing impurities, by-products, or excess reagents from reaction mixtures.
