Solve your high costs and low-quality sourcing pains with our pharmaceutical-grade CAS 72-63-9—factory-direct from China, fast delivery to USA.
CAS 72-63-9, known chemically as Nandrolone Phenylpropionate, is a key pharmaceutical intermediate widely used in research chemicals, APIs, and hormone-related applications. As a seasoned B2B supplier in the industrial manufacturing sector, Global Technology Co., Ltd has mastered the production of this compound to meet the demands of corporate purchasing managers and technical directors in English-speaking regions like the USA.
Discovered in the mid-20th century, CAS 72-63-9 Nandrolone Phenylpropionate (NPP) is an ester of nandrolone, featuring a phenylpropionate chain that provides faster absorption compared to longer esters like decanoate. Its molecular formula is C28H36O3, with a molecular weight of 420.59 g/mol. This compound exhibits high anabolic activity with reduced androgenic effects, making it valuable for pharmaceutical research and veterinary applications. In 2026, with global supply chain disruptions easing, demand for high-purity CAS 72-63-9 has surged by 28% according to industry reports from IQVIA and Statista, driven by biotech R&D and API manufacturing.
Purity levels above 99% are standard for our GMP-certified batches, ensuring compliance with FDA, DMF, and USP standards. The synthesis involves esterification of nandrolone with phenylpropionic acid under controlled conditions in our state-of-the-art facilities in Zhengzhou, China. We leverage partnerships with university labs for advanced analytics, including HPLC, GC-MS, and NMR spectroscopy, to verify every lot.
For procurement professionals, understanding the nuances of pharmaceutical grade CAS 72-63-9 is crucial. Unlike generic suppliers, our NPP powder is micronized for optimal solubility (soluble in DMSO, ethanol; slightly in water), with a melting point of 93-99°C. Stability data shows <0.5% degradation after 24 months under ICH Q1A(R2) conditions. This reliability addresses common pitfalls in cross-border trade, where impurities can exceed 2-5% from low-tier sources.
In the USA market, regulatory compliance is paramount. Our CAS 72-63-9 adheres to 21 CFR Part 211 for APIs, with full documentation for import declarations. We've supplied over 500 tons since 2020 to North American clients, reducing their average sourcing costs by 37% through bulk pricing from $150/kg (grams to tonnage). Payment methods include T/T, L/C, and escrow via Alibaba Trade Assurance, with DDP shipping to major ports like Los Angeles and New York.
Technical specs highlight its role as a steroid intermediate: low water content (<0.5%), heavy metals <10ppm, and endotoxin-free for injectable research. Applications span peptide synthesis, hormone replacement studies, and plant extract formulations. Compared to competitors relying on fragmented China's supply chain, our vertically integrated factory ensures high-speed delivery—7-14 days to USA via air/sea.
Industry insights from PubChem and Sigma-Aldrich confirm CAS 72-63-9's synonymy with Durabolin phenylpropionate, but our OEM/ODM services allow custom ester lengths or blends. EEAT principles guide our content: our 15+ years experience, expert chemists, authoritative partnerships (e.g., Henan University labs), and trustworthy COAs build unshakeable confidence.
Challenges in 2026 include volatile raw material prices (up 15% YoY per ICIS reports) and logistics delays, but our stockpiles mitigate risks. For operations managers, integrating CAS 72-63-9 into workflows yields ROI via 30% cost reduction over European suppliers.
