Lidocaine Impurities and Lidocaine

Daicel Pharma offers the best quality Lidocaine impurities, such as N-desethyl Lidocaine (TFA salt) and N-Nitroso-desethyl lidocaine (Mixture of isomers). It is vital for evaluating the quality, stability, and biological safety of Lidocaine. In addition, Daicel Pharma specializes in the custom synthesis of Lidocaine impurities and ensures their worldwide delivery.

Lidocaine [CAS: 137-58-6], or Lignocaine, is a tertiary amine and a local anesthetic agent. It also has analgesic and antiarrhythmic uses. Lidocaine with vasopressors aids in local anesthesia. It helps in advanced airway management during tracheal intubation.

Lidocaine stabilizes the neuronal membrane. It inhibits ionic fluxes needed for impulse initiation and conduction, thus causing local anesthetic action.

Lidocaine Impurities and Synthesis

Impurities may occur during the synthesis of Lidocaine ¹ that affect drug safety and efficacy. They form during the synthesis, storage, or degradation of Lidocaine. It is necessary to control and monitor the impurities of Lidocaine to improve drug safety, efficacy, and storage.

Daicel Pharma offers a comprehensive Certificate of Analysis (CoA) for Lidocaine impurities, which includes N-desethyl Lidocaine (TFA salt) and N-Nitroso-desethyl lidocaine (Mixture of isomers). The CoA is from a cGMP-compliant analytical facility. It contains the complete characterization data such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity². We give additional data like 13C-DEPT and CHN on request. Daicel Pharma can prepare any unidentified Lidocaine impurity or degradation product. In addition, Daicel Pharma offers a highly purified deuterium-labeled standard of N-Nitroso-desethyl lidocaine-d5 (Mixture of isomers) for bioanalytical research and BA/BE studies. We also provide a complete characterization report on delivery.
