General Information

Minocycline Impurities and Minocycline  

Daicel Pharma synthesizes high-quality Minocycline impurities like 4-EpiMinocycline, 7-Monomethyl Minocycline, Minocycline Dehydro analogue, 12-Imino-delta-Minocycline, and more, which are crucial in the analysis of the quality, stability, and biological safety of the active pharmaceutical ingredient Minocycline. Moreover, Daicel Pharma offers custom synthesis of Minocycline impurities and delivers them globally.

Minocycline [CAS: 10118-90-8] is a second-generation tetracycline antibiotic that is semi-synthetic. It has many applications in treating various infectious and non-infectious diseases. The drug has comparable anti-infectious properties to other tetracyclines.

Minocycline: Use and Commercial Availability 

Minocycline is available in various forms and treats numerous medical conditions. Oral and topical forms manage inflammatory acne lesions. The drug is also available in oral and intravenous formulations to treat infections caused by susceptible microorganisms. Some microorganisms treated by Minocycline include Mycoplasma pneumoniae, Chlamydia trachomatis, Yersinia pestis, and Escherichia coli. Minocycline is available under several brand names, including Amzeeq, Arestin, Dynacin, Minocin, Minocycline Hydrochloride, Minolira, Solodyn, Ximino, and Zilxi.

Minocycline Structure and Mechanism of Action

The chemical name of Minocycline is (4S,4aS,5aR,12aS)-4,7-Bis(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,10,12,12a-tetrahydroxy-1,11-dioxo-2-naphthacenecarboxamide. Its chemical formula is C₂₃H₂₇N₃O_7, and its molecular weight is approximately 457.5 g/mol.

Minocycline exerts its antimicrobial effects by inhibiting bacterial protein synthesis.

Minocycline Impurities and Synthesis

Minocycline can undergo degradation, resulting in the formation of impurities. The impurities that form during the degradation of Minocycline include 4-epiMinocycline and other related compounds. The impurities are due to pH, temperature, and storage conditions. Controlling these factors during the manufacturing¹, storage, and use of Minocycline can help minimize impurity formation and maintain product quality.

Daicel offers a Certificate of Analysis (CoA) from a cGMP-compliant analytical facility for Minocycline impurity standards, 4-EpiMinocycline, 7-Monomethyl Minocycline, Minocycline Dehydro analogue, 12-Imino-delta-Minocycline, and more. The CoA includes complete characterization data, such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity². We also provide 13C-DEPT and CHN if requested. We give a complete characterization report on delivery. Daicel has the technology and expertise to prepare any unknown Minocycline impurity or degradation product.
