General description

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Lidocaine hydrochloride is an amide type local anaesthetic that belongs to the class of 1b antiarrhythmics. It is used for regional nerve blocks and infiltrative administration of anaesthesia. It prevents the entry of sodium ions into nerve endings, at the site of pain, and disrupts the electrical signal from reaching the brain.


This pharmaceutical secondary standard can also be used as follows:
  • Sensitive determination of lidocaine hydrochloride and cetylpyridinium chloride in their binary mixtures in different pharmaceutical formulations by three spectrophotometric-based methods
  • Simultaneous analysis of aminoacridine hydrochloride and lidocaine hydrochloride in bulk powder and pharmaceutical formulation by high-performance liquid chromatography (HPLC) and thin-layer chromatography (TLC)-densitometric methods
  • Quantification of ceftriaxone sodium and lidocaine HCl in human plasma samples by high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS)
  • Quantitative analysis of lidocaine hydrochloride and miramistin in a wound healing gel sample by high-performance liquid chromatography (HPLC) combined with UV detection
  • Development of a method based on liquid–liquid extraction of nifedipine and lidocaine hydrochloride from human plasma samples for their subsequent analysis by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS)
  • Dispersive liquid-liquid microextraction (DLLME) followed by attenuated total reflectance-Fourier transform infrared measurement of dry films for the determination of lidocaine hydrochloride in human urine sample

Biochem/physiol Actions

Na+ channel blocker; class IB antiarrhythmic that is rapidly absorbed after parenteral administration

Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
