In the rigorous process of pharmaceutical development and manufacturing, the identification, control, and understanding of impurities are of utmost importance. Impurities, even in trace amounts, can significantly impact the safety and efficacy of a drug product. Therefore, sourcing high-purity impurity standards, such as Doxofylline Impurity 3 (also known as 9-(1,3-Dioxolan-2-ylmethyl)-3,9-dihydro-1,3-dimethyl-1H-purine-2,6-dione, CAS: 1174289-18-9), is a critical requirement for pharmaceutical companies worldwide.

As a specialized manufacturer of pharmaceutical intermediates and related compounds, NINGBO INNO PHARMCHEM CO.,LTD. understands the intricate needs of drug developers. We provide meticulously characterized impurity standards that are essential for various stages of pharmaceutical R&D. These standards are used for method development, validation of analytical techniques, and routine quality control testing to ensure that final API batches meet all regulatory requirements, including ICH Q3A/Q3B guidelines.

The accurate quantification and characterization of impurities allow researchers to develop robust analytical methods, such as High-Performance Liquid Chromatography (HPLC) or Gas Chromatography (GC). By having a reliable reference standard like 9-(1,3-Dioxolan-2-ylmethyl)-3,9-dihydro-1,3-dimethyl-1H-purine-2,6-dione, pharmaceutical scientists can accurately identify and quantify this specific impurity in their Doxofylline synthesis or related processes. This capability is vital for ensuring batch-to-batch consistency and the overall quality of the drug substance.
