The field of life sciences constantly seeks innovative materials to push the boundaries of research and therapeutic development. Among the advanced biochemicals available, functionalized lipids like 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-[3-(2-pyridyldithio)propionate] (sodium salt), or DPPE-PDP, are gaining prominence. This article delves into the essential properties and widespread applications of DPPE-PDP, highlighting its importance for researchers and manufacturers in the pharmaceutical and biotechnology sectors. Understanding where to buy DPPE-PDP and its key characteristics is vital for successful project outcomes.

DPPE-PDP is a synthetic phospholipid derivative characterized by a dipalmitoyl lipid chain and a phosphoethanolamine headgroup modified with a pyridyldithio propionate moiety. This structure provides it with unique chemical properties, making it distinct from standard phospholipids. Typically appearing as a white powder with high purity (often exceeding 98%), DPPE-PDP is stable when stored under recommended conditions, usually at -20°C. Its molecular weight and formula are critical parameters for precise formulation calculations, and these details are readily available from reputable manufacturers.

The primary applications of DPPE-PDP stem from its functional group, which allows for its integration into various advanced systems. In drug delivery, it serves as a key component in the formation of liposomes and lipid nanoparticles (LNPs). These nanoparticles can encapsulate drugs, protecting them from degradation and facilitating their targeted delivery to specific sites within the body. The pyridyldithio group can also be utilized to create pH-sensitive or redox-responsive delivery systems, leading to triggered drug release. Researchers looking to purchase this compound often seek it for these precise delivery mechanisms.

Beyond therapeutics, DPPE-PDP is also recognized for its utility in medical imaging, particularly as a component in MRI contrast agents. Its paramagnetic properties can be harnessed to enhance image clarity and visualize biological processes or the distribution of drug-carrying nanoparticles. This dual role in both treatment and diagnosis underscores its versatility and value in modern medical research.

For R&D scientists and procurement managers, sourcing DPPE-PDP requires careful consideration of the supplier. It is essential to identify manufacturers who can provide consistently high-purity material, along with comprehensive documentation such as CoAs. The availability of DPPE-PDP from reliable suppliers, including those in China known for quality chemical manufacturing, ensures that research projects and product development pipelines remain on track. Exploring purchase options for DPPE-PDP from established suppliers is a critical step for innovation in life sciences.
