The synthesis of Active Pharmaceutical Ingredients (APIs) is a complex process that relies heavily on the quality and purity of intermediate compounds. For the widely used antidepressant Doxepin, a key intermediate is Dibenz[b,e]oxepin-11(6H)-one. The integrity of this intermediate directly impacts the efficacy and safety of the final Doxepin product. This article explores the importance of sourcing high-purity Dibenz[b,e]oxepin-11(6H)-one and the role of reputable manufacturers in ensuring its quality.

Dibenz[b,e]oxepin-11(6H)-one, with CAS number 4504-87-4, is a light brown crystalline powder that serves as a fundamental building block in the multi-step synthesis of Doxepin. The pharmaceutical industry demands stringent purity standards for all raw materials and intermediates. For Dibenz[b,e]oxepin-11(6H)-one, specifications often include an assay of ≥99.0%, with tight controls on moisture content (≤0.2%) and individual impurities (≤0.5%). Adherence to these specifications is not merely a regulatory formality but a critical step in preventing the formation of unwanted byproducts and ensuring the desired therapeutic profile of the final drug.

When pharmaceutical companies look to buy Dibenz[b,e]oxepin-11(6H)-one, they prioritize suppliers who can guarantee consistency and purity. The selection of a reliable supplier, particularly one based in regions known for robust chemical manufacturing like China, is paramount. NINGBO INNO PHARMCHEM CO.,LTD. understands these demands.
