Welcome to Orihar Biomedical

Orihar Biomedical is a specialized supplier of nucleoside products and fine chemical intermediates. We work with research institutions, biotechnology companies, pharmaceutical manufacturers and distributors that need clearly identified products, responsive communication and practical support from initial inquiry through delivery.

Our nucleoside-related portfolio includes DNA and RNA phosphoramidites, LNA and ENA building blocks, PMO monomers, modifiers, linkers and other small nucleic acid-related products. These materials support oligonucleotide research and development, analytical method work and process exploration. Our fine chemical portfolio includes pyridine and heterocyclic compounds, halogenated aromatic intermediates, pharmaceutical intermediates, ketones, aldehydes, esters and specialty building blocks.

Customers often need more than a catalogue number. A project may require a specific protecting group, purity target, package size, documentation set or delivery schedule. Orihar therefore handles each inquiry according to the product identity and intended research or manufacturing stage. When a standard catalogue item does not meet the requirement, customers may submit a structure, CAS number, target specification and requested quantity for a custom evaluation.

Our working approach is straightforward. We first confirm the product name, structure or CAS number and the requested specification. We then review availability, technical feasibility, quantity and lead time. Before an order moves forward, the customer receives a clear quotation and the available product documentation. This process helps reduce ambiguity, particularly for modified nucleosides and specialty intermediates with similar abbreviations or closely related structures.

As a growing company, we are building our product range and service system around the needs of international customers. We value accurate product communication, timely feedback and long-term cooperation. This website will be updated with new products, technical introductions and practical information about nucleoside chemistry and fine chemical sourcing.

If you are looking for a listed product or a compound that is not yet shown in our catalogue, please send us the English name, CAS number or chemical structure, required purity, quantity and destination. Our team will review the request and respond with the next steps.
