In the complex world of pharmaceutical manufacturing, the quality and availability of intermediates are paramount. One such critical compound is 17-Iodoandrosta-5,16-dien-3beta-ol 3-acetate, identified by its CAS number 114611-53-9. This steroid derivative plays a pivotal role in the synthesis of several important active pharmaceutical ingredients (APIs), most notably Abiraterone Acetate, a drug widely used in the treatment of prostate cancer. Understanding the properties and sourcing of this intermediate is essential for any pharmaceutical company aiming for efficient and high-quality drug production.

17-Iodoandrosta-5,16-dien-3beta-ol 3-acetate is characterized by its chemical formula C21H29IO2 and a molecular weight of approximately 440.36 g/mol. It typically presents as a white to off-white powder, with manufacturers often guaranteeing a high purity of 98% or higher. This purity is crucial, as even minor impurities can affect the efficacy and safety of the final drug product. As a key building block, its consistent supply is non-negotiable for drug developers and manufacturers. Companies seeking to buy this intermediate often look for reliable manufacturers who can guarantee not only quality but also a stable supply chain, particularly when large-scale production is involved.

The primary application driving the demand for 17-Iodoandrosta-5,16-dien-3beta-ol 3-acetate is its use in the multi-step synthesis of Abiraterone Acetate. Abiraterone Acetate functions by inhibiting CYP17A1, an enzyme essential for androgen biosynthesis, thereby reducing testosterone levels in patients with advanced prostate cancer. The synthetic pathway leading to Abiraterone Acetate relies heavily on the precise chemical structure and high purity of this iodo-steroid intermediate. Therefore, sourcing this compound from a reputable manufacturer becomes a strategic decision for pharmaceutical companies aiming to maintain production efficiency and product integrity.

When looking to purchase 17-Iodoandrosta-5,16-dien-3beta-ol 3-acetate, potential buyers will consider several factors. These include the supplier's track record, their manufacturing capabilities, quality control processes, and their ability to provide comprehensive documentation such as Certificates of Analysis (CoA) and Material Safety Data Sheets (MSDS). For businesses operating on a global scale, the location of the manufacturer can also be significant, with many opting for suppliers in regions known for their robust chemical manufacturing sectors, such as China. The price of the intermediate is, of course, a critical consideration, but it must be balanced against quality and reliability. Securing a consistent supply of this vital pharmaceutical intermediate ensures that drug production lines remain operational, meeting the demands of patients worldwide. As such, partnering with an experienced manufacturer is key to navigating the complexities of pharmaceutical intermediate sourcing.
