For procurement specialists and R&D scientists in the pharmaceutical industry, sourcing critical intermediates like Dibenz[b,e]oxepin-11(6H)-one (CAS 4504-87-4) requires careful consideration of several factors. As a key component in the synthesis of Doxepin, its availability and quality can significantly impact production timelines and the final drug product's regulatory compliance. This guide outlines what to look for when sourcing this important chemical, emphasizing the benefits of partnering with experienced manufacturers and suppliers.

The primary concern for any buyer is product quality. Dibenz[b,e]oxepin-11(6H)-one, when used as a pharmaceutical intermediate, must meet stringent purity standards. A typical specification from a reputable supplier will indicate an assay of ≥99.0%, with very low limits for moisture (≤0.2%) and individual impurities (≤0.5%). These parameters are vital for ensuring the integrity of the downstream synthesis process and ultimately, the safety and efficacy of the API. When inquiring about price, always ensure that the purity specifications are clearly stated and understood.

Reliability of supply is another crucial factor. Pharmaceutical production schedules are often tight, and any disruption in the supply chain can lead to significant delays and financial losses. This is where partnering with a well-established manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. becomes invaluable.

A good supplier will not only offer competitive prices but also provide comprehensive technical support, including Certificates of Analysis (CoA) and detailed product specifications. They should be transparent about their manufacturing processes and quality assurance systems. For Dibenz[b,e]oxepin-11(6H)-one, understanding its role as a Doxepin intermediate is key to appreciating the critical nature of its quality.
