Description

• General description: Cotinine is an alkaloid found in tobacco as well as a major urinary metabolite of nicotine. This stable-labeled internal standard is suitable for quantitation of cotinine levels in urine, blood, and saliva for GC/MS or LC-MS/MS applications in nicotine testing or clinical and diagnostic testing of nicotine biomarkers.
• Application: (±)-Cotinine-d₃ solution in nicotine metabolism research: This stable isotope-labeled compound is utilized in the HPLC-MS analysis of nicotine and cotinine across various biological matrices, highlighting its critical role in advancing our understanding of nicotine metabolism and exposure in biomedical studies (Jin et al., 2022).Biomarker analysis in passive smoking: Cotinine-d₃ serves as an internal standard in the precise quantification of urinary cotinine, aiding in the assessment of second-hand smoke exposure, particularly in pediatric health studies (Wang et al., 2014).Enhanced analytical techniques for smoking cessation: Employed in a sophisticated UPLC-MS/MS setup, cotinine-d₃ is crucial for quantifying smoking-related biomarkers in clinical trials aimed at evaluating smoking cessation interventions, ensuring accurate and sensitive biomarker tracking (Dobrinas et al., 2011).
