NEW YORK, NY, March 19, 2026 /24-7PressRelease/ -- Protheragen, an ISO9001 certified supplier of specialty chemicals, offers a full portfolio of high-quality peptide intermediates, pharmaceutical intermediates, and one-stop custom intermediate solutions, empowering global pharmaceutical companies, biotech firms, and research institutions to accelerate drug research, development, and large-scale production processes.

As core building blocks for complex drug molecule synthesis, Protheragen's peptide intermediates and pharmaceutical intermediates have become indispensable in the R&D and manufacturing of a wide spectrum of pharmaceuticals, including anticancer drugs, antimicrobial peptide drugs, metabolic disease therapeutics, and antiviral drugs. They also play a critical role in the development of diagnostic reagents and vaccines. Boasting high purity, batch-to-batch consistency, and a diverse product range with more than 2,000 intermediates available, Protheragen's intermediate products meet the rigorous requirements of various drug development stages.

Peptide intermediates from Protheragen serve as the foundation for peptide chain synthesis, covering a rich array of categories such as protected amino acids, specialty amino acids, linkers, amino acid derivatives, Fmoc-Amino Acids, Boc-Amino Acids and fluorescent labeling reagents. These products leverage the high activity and low toxicity advantages of peptide drugs, providing strong support for R&D in cancer treatment, metabolic diseases, and infectious disease treatment fields. Meanwhile, Protheragen's pharmaceutical intermediates, including heterocyclic compounds, chiral intermediates, and boron derivatives, form the core framework of active pharmaceutical ingredients (APIs) for small-molecule drugs, and are widely applied in the synthesis of chemical drugs for antiviral and cardiovascular disease therapies.

Recognizing the diverse and personalized needs of global drug development, Protheragen goes beyond intermediate product supply to provide tailored custom intermediate services, covering both custom pharmaceutical intermediates and custom peptide intermediates. For custom pharmaceutical intermediates, Protheragen excels in synthesizing complex structures such as heterocyclic compounds, chiral molecules, fluorides and boronates, with R&D and production capabilities ranging from laboratory processes to commercial manufacturing. In the field of custom peptide intermediates, Protheragen utilizes advanced technologies including solid-phase peptide synthesis, liquid-phase peptide synthesis, and fragment condensation, and is capable of complex modifications such as phosphorylation, glycosylation and fluorescent labeling, as well as synthesizing linear and cyclic peptides from short to medium lengths.

To ensure the superior quality of all intermediates, Protheragen has a complete supporting service solution covering purification and separation, comprehensive analysis, physicochemical testing, and stability testing. Its advanced purification and separation platform customizes optimal purification strategies based on intermediate properties and purity requirements; the professional analysis service provides accurate structural confirmation and purity determination, and issues formal Certificates of Analysis (CoA); the full range of physicochemical testing includes melting point, density, optical rotation and other key indicators; and the scientific stability testing provides data support for optimal storage conditions and regulatory filing.
