General Information

Dexrazoxane Impurities and Dexrazoxane

Daicel Pharma synthesizes Dexrazoxane impurities of exceptional quality, such as Dexrazoxane Impurity-A, Dexrazoxane Impurity-C, and Dexrazoxane Impurity-D. These impurities are crucial to assess the purity, reliability, and safety of Dexrazoxane, an active pharmaceutical ingredient. Besides, Daicel Pharma provides custom synthesis of Dexrazoxane impurities to meet clients’ demands for delivery worldwide.

Dexrazoxane [CAS: 24584-09-6], the (+)-enantiomorph of razoxane, exhibits iron-chelating, chemoprotective, cardioprotective, and antineoplastic properties. It acts as an antimitotic agent while also possessing immunosuppressive effects. Dexrazoxane provides cardioprotection against anthracycline toxicity by inhibiting the formation of a toxic iron-anthracycline complex.

Dexrazoxane: Use and Commercial Availability  

Dexrazoxane, an FDA-approved cardioprotective drug, has demonstrated its effectiveness in managing cardiac toxicity associated with anthracycline-based chemotherapy in cancer patients, particularly those with advanced breast cancer, soft tissue sarcomas, or small-cell lung cancer. It treats tissue damage caused by anthracyclines. Dexrazoxane is available under brand names, including Totect and Zinecard.

Dexrazoxane Structure and Mechanism of Action Dexrazoxane Structure and Mechanism of Action

The chemical name of Dexrazoxane is 4,4′-[(1S)-1-Methyl-1,2-ethanediyl]bis[2,6-piperazinedione]. Its chemical formula is C11H16N4O4, and its molecular weight is approximately 268.27 g/mol.

Dexrazoxane readily penetrates cell membranes and is a cyclic derivative of EDTA.

Dexrazoxane Impurities and Synthesis

During the synthesis1 of Dexrazoxane, impurities generate as byproducts. They may originate from starting materials, reagents, or reaction intermediates used in manufacturing. It is necessary to identify and characterize these impurities to ensure the purity and safety of the final product. Analytical techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry (MS) help in impurity profiling and quantification. Manufacturers of Dexrazoxane closely monitor impurities to meet regulatory standards and implement purification methods to minimize their presence, ensuring the highest quality of the drug for therapeutic use.

Daicel Pharma offers a Certificate of Analysis (CoA) for Dexrazoxane impurity standards, such as Dexrazoxane Impurity-A, Dexrazoxane Impurity-C, and Dexrazoxane Impurity-D, generated from an analytical facility compliant with cGMP standards. The CoA includes a comprehensive characterization report comprising data from techniques like 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. Furthermore, on request, we give additional data like 13C-DEPT and CHN. Daicel Pharma can synthesize unknown Dexrazoxane impurities or degradation products. A complete characterization report accompanies every delivery.


Frequently Asked Questions

The common impurities in Dexrazoxane may include related substances, degradation products, residual solvents, and other process-related contaminants. They vary depending on the synthetic route and manufacturing process.

Impurities in Dexrazoxane are removed during purification steps such as crystallization, filtration, chromatography, and other separation techniques. These methods help isolate the desired product while removing impurities in the reaction mixture.

Water is a solvent used in analyzing many impurities in Dexrazoxane.

Dexrazoxane impurities are stored at a controlled room temperature between 2-8 °C or as indicated on the Certificate of Analysis (CoA).
