Nitrobenzene

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

This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Nitrobenzene can be used as an internal standard to quantify monoacylated aromatic compounds such as 4-acetylanisole, 4-acetylisobutylbenzene, 2-acetylthiophene, 2-acetylfuran, and N-nitrosomorpholine using Gas chromatography and HPLC techniques. It can also be used as an internal standard in quantitative ¹H NMR spectroscopy to determine product yields for the Heck reactions, and chlorinated arenes and heteroarenes.

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

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.
