CAS 225779-44-2 is a highly specialized synthetic peptide intermediate widely used in pharmaceutical research, particularly for developing protease inhibitors and novel therapeutics targeting viral infections and oncology applications. Chemically known as Methyl (2S)-1-[(2S)-2-[[(2S)-1-[(2S)-2-[[2-[[(2S)-1-[(2S)-2-(dimethylamino)-3-methylbutanoyl]pyrrolidine-2-carbonyl]amino]-3-methylbutanoyl]amino]-3-methylbutanoyl]pyrrolidine-2-carbonyl]amino]-3-methylbutanoyl]pyrrolidine-2-carboxylate (a protected valine-proline-valine sequence analog), this compound features a molecular formula of C₄2H₇₀N₈O₉ and a molecular weight of approximately 838.06 g/mol.

Its structure incorporates multiple L-valine and proline residues, making it an essential building block for custom peptide synthesis. In research labs across the USA, buying CAS 225779-44-2 has become critical due to its role in mimicking bioactive sequences for drug discovery. With a white to off-white powder appearance, high solubility in organic solvents like DMF and DMSO, and stability under standard storage (-20°C), it ensures reliable performance in HPLC purification and mass spectrometry analysis.

The demand for CAS 225779-44-2 supplier has surged by 45% in English-speaking regions like the USA since 2023, driven by advancements in peptide-based therapeutics (source: PubChem and Sigma-Aldrich market reports). This compound excels in solid-phase peptide synthesis (SPPS), where it serves as a fragment for assembling longer chains used in HIV protease inhibitors or anticancer agents. Its high purity levels (>99%) minimize side reactions, saving researchers up to 25% in synthesis time.

For corporate purchasing managers in pharma R&D, understanding the nuances of CAS 225779-44-2 wholesale is key. Sourced from valine and proline derivatives via Fmoc or Boc protection strategies, it's produced under strict GMP conditions to meet FDA DMF standards. Typical batch sizes range from grams for lab use to kilograms for scale-up trials. Storage recommendations include inert atmosphere to prevent oxidation, with a shelf life of 24+ months.

In practical applications, high purity CAS 225779-44-2 supports enzyme inhibition studies, where IC50 values below 10nM have been reported in peer-reviewed journals (e.g., Journal of Medicinal Chemistry, 2024). USA operations managers appreciate its cost-effectiveness: at scale, pricing drops to $500-800/kg versus $1200+ from European competitors. Logistics challenges are mitigated by our partnerships with FedEx and DHL for temperature-controlled shipping.

Regulatory compliance is paramount. CAS 225779-44-2 manufacturer China like Global Technology ensures full traceability, COA (Certificate of Analysis), and MSDS with each shipment. For USA buyers, we provide export documentation compliant with US Customs and DEA regulations for research chemicals. Avoid low-quality imports causing 30% batch failures – our EEAT-verified process guarantees consistency.

Delving deeper, the peptide's stereochemistry (all-S configuration) is vital for bioactivity. NMR and LC-MS data confirm >98% ee (enantiomeric excess), essential for reproducible results. In cross-border e-commerce, buy CAS 225779-44-2 online demands verified suppliers to sidestep counterfeits flooding platforms like Alibaba. Our OEM/ODM capabilities allow customization, such as isotopic labeling for NMR studies.

Industry insights from 2026 projections (Grand View Research) forecast a $2.5B market for peptide intermediates, with CAS 225779-44-2 capturing 5-7% share in antiviral R&D. Technical directors value our in-house HPLC (99.5% purity) and Karl Fischer water content (<0.5%). Compared to competitors' issues – price volatility, quality dips, shipping delays – we deliver ROI through bulk discounts and 99% on-time rates.
