Benzisothiazolinone-¹³C₅(CAT: R048490) is a carbon-13 stable isotope-labeled analog of benzisothiazolinone (BIT), a widely used antimicrobial and preservative in industrial and consumer products. The incorporation of five ¹³C atoms enables precise quantification and differentiation in mass spectrometry-based analytical methods, making it an ideal internal standard for residue analysis in complex matrices. Benzisothiazolinone-¹³C₅ supports research on environmental exposure, toxicology, and regulatory compliance by facilitating accurate detection and monitoring of BIT levels. It is particularly valuable in studies involving product safety, degradation pathways, and human health risk assessment. Suitable for LC-MS and GC-MS applications in environmental and toxicological research.
