Watertown, MA – November 24, 2025 – Biopharma PEG Scientific Inc. announced the availability of a broad range of in-stock monodispersed PEG derivatives at highly competitive prices, supporting researchers working in antibody–drug conjugates (ADCs), nanoparticle and LNP delivery systems, diagnostics, and biomaterials.

Biopharma PEG specializes in PEG derivatives, including monodispersed, polydispersed, and multi-arm PEGs, offered in both GMP and non-GMP grades. By keeping key monodispersed PEGs on the shelf and ready to ship, the company aims to help R&D teams reduce lead times, manage project costs, and ensure reliable supply for critical programs.

Why Monodispersed PEGs?

Conventional PEG mixtures contain a distribution of chain lengths, which can introduce variability in complex modalities such as ADCs or targeted nanomedicines.

In contrast, monodispersed PEGs offer:

• Uniform chain length and defined molecular weight
• Higher purity and clearer analytical profiles
• Improved reproducibility in conjugation and formulation

  In-Stock Monodispersed PEGs – Ready to Ship, Competitive Pricing

  Biopharma PEG currently maintains inventory of the following monodispersed PEGs, available for immediate shipment and offered at very competitive prices for both research and scale-up:

  N3-PEG11-NH2 | Boc-NH-PEG11-N3 | N3-PEG6-OH | N3-PEG4-OH | N3-PEG3-COOH |N3-PEG3-SPA | OH-PEG9-OH | OH-PEG8-OH | OH-PEG6-COOH | NH2-PEG4-OH | COOH-PEG4-NH2·HCl | OH-PEG3-CH2CH2COOtBu etc

  These reagents are widely used in:

• ADC linker and bioconjugation chemistry
• Nanoparticle, liposome, and LNP surface modification
• Imaging and diagnostic probe development
• Hydrogel and advanced biomaterial design

  “Our commitment is to provide products like our monodispersed PEGs with the reliability and precision required to accelerate drug discovery and development projects,” said Sonia Lee, Business Development Manager at Biopharma PEG.

  With products in stock and ready to ship, teams can move quickly from design to experiment without waiting for long custom synthesis timelines.

  Quality, Scalability, and Technical Support

  All Biopharma PEG products are manufactured to high quality standards, with:

• Purity typically >95%
• Low impurity levels and stable batch-to-batch quality
• Scalable production from milligrams to hundreds of kilograms
• GMP-capable manufacturing for clinical and commercial stages

To support this, Biopharma PEG is equipped with state-of-the-art analytical instrumentation and an experienced scientific team, including NMR, 400 MHz, HPLC,  MALDI-TOF MS, GC, LC, etc.

This infrastructure supports comprehensive structural confirmation, impurity profiling, and consistent quality control across production scales.
