For procurement managers in the pharmaceutical, biotechnology, and materials science sectors, sourcing critical chemical intermediates requires diligence and a focus on reliability, quality, and cost-effectiveness. The Boc-protected amino PEG linker (CAS 101187-40-0) is one such intermediate that has become increasingly vital for a range of advanced applications, from drug delivery systems to bioconjugation strategies.

When evaluating suppliers for this specific compound, known commonly as Boc-NH-PEG3-NH2, key considerations include product purity, consistency of batch-to-batch quality, available quantities, lead times, and competitive pricing. Understanding the chemical's structure and its primary applications is also important for ensuring you are procuring the right material for your research and development needs.

The Boc-protected amino PEG linker is a heterobifunctional molecule characterized by a polyethylene glycol (PEG) chain. One terminus features a free primary amine, readily reactive with various electrophiles, while the other terminus carries a Boc-protected amine. This Boc protecting group can be selectively removed under acidic conditions, revealing a second amine functionality. This controlled reactivity is invaluable for multi-step synthesis and the precise assembly of complex molecular architectures, such as antibody-drug conjugates (ADCs) or targeted delivery vehicles.

The hydrophilic nature of the PEG spacer contributes significantly to improved solubility and pharmacokinetic properties when incorporated into therapeutic agents. This makes it a preferred choice for enhancing the performance of drugs and biomolecules. When you need to buy this linker, seeking a supplier that can guarantee high purity (e.g., ≥98%) is essential to avoid potential complications in sensitive synthesis pathways or biological assays.
