Basic Website Profile

This is the official website of Beijing J9 Direct Group Technology Co., Ltd., a STAR Market-listed high-tech enterprise that has focused on the field of pharmaceutical-grade polyethylene glycol (PEG) derivatives in China for over 20 years. Its core business covers the production and sales of pharmaceutical-grade PEG derivatives, as well as supporting PEGylation technical services, making it one of the leading players in this niche segment in China.

Core Products and Services

The website lists 8 main categories of publicly available products, including high-molecular-weight PEG derivatives, monodisperse PEG derivatives, PEG linkers, LNP delivery system excipients, click chemistry reagents, PEG raw materials for medical devices, PEG standards, and long-acting polypeptide fatty acid side chains. The company also owns Silky Rose, its own aesthetic medicine brand. In total, it offers more than 2000 products, with over 600 products kept in regular stock.

For technical services, the company provides synthesis method development, analytical method development, and PEGylation technical services. It also assists clients with quality research and IND applications, supporting full-process needs from candidate drug screening to clinical trial application. Its standout core products include PEG linkers for PROTAC, as well as 4 core LNP delivery system components that have completed domestic pharmaceutical excipient registration, covering the current popular R&D needs of nucleic acid drugs and targeted protein degradation drugs.

Advantages and Disadvantages

Advantages:

• Sufficient production capacity: The company has two production bases in Tianjin and Liaoning. Once the new Liaoning base reaches full production, it will expand current capacity by 6 to 10 times, meeting the large-scale supply requirements for the commercialization stage.
• High product compliance: Products follow cGMP and ICH Q7 standards, and core excipients have completed pharmaceutical registration, making them suitable for innovative drug application.
• Complete product coverage: It can meet the one-stop procurement needs of pharmaceutical companies for all types of PEG derivatives.

Disadvantages:

• Poor website user experience: Navigation is repetitive and redundant. No product pricing or minimum order quantity information is publicly available, so customers have to contact sales offline to get a quote. The procurement threshold is relatively high, and it is not suitable for small-batch procurement needs of small and medium-sized laboratories.

Accessibility & Target Audience

This website can be accessed directly within China. Its full-Chinese interface is tailored for domestic clients, making it a suitable choice for domestic innovative drug companies, nucleic acid vaccine R&D institutions, PROTAC R&D teams, aesthetic medicine product manufacturers, and university biomedical research institutions when sourcing pharmaceutical-grade PEG raw materials.
