2-Cyano-4'-methylbiphenyl (CAS 114772-53-1)

Application and positioning

The key starting material for the sartan family of angiotensin II receptor antagonists — valsartan, irbesartan and losartan routes all trace back to this biphenyl. Supplied as high-purity crystals with tight control on isomer and brominated impurities; available from pilot to multi-ton scale. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots; process and regulatory documentation is coordinated case by case with the manufacturing site.

Quality and documentation
