Tetrahydrozoline EP Impurity A (CAS 56536-96-0) is identified as α-cyanotetraline, also named 1,2,3,4-tetrahydronaphthalene-1-carbonitrile. With molecular formula C11H11N and molecular weight 157.21 g/mol, it is a benzylic nitrile structurally related to the tetralin scaffold. In tetrahydrozoline manufacture, such an impurity may arise from side reactions during construction of the fused bicyclic core or from incomplete downstream purification. Because benzylic nitriles can persist at low levels and require stringent control, determination typically relies on LC-MS/MS or GC-MS, supported by HPLC or GC separation. Its specification is relevant to compendial impurity profiling and related genotoxic impurity assessment.Request a Quote
