This chemical is primarily used in the field of analytical chemistry as a labeled internal standard or reference compound in mass spectrometry. Its deuterated form (iso-propyl-d7) allows for precise tracking and quantification of similar non-deuterated compounds in complex mixtures, particularly in environmental or biological samples. It is also employed in metabolic studies to understand the behavior and degradation pathways of related pyridine derivatives. Additionally, it serves as a key intermediate in the synthesis of more complex deuterated compounds used in pharmaceutical research and development.
