High-purity reference standard for pesticide residue analysis, environmental monitoring, and agricultural chemistry

Sigma-Aldrich 3,5,6-Trichloro-2-pyridinol (TCP) is a PESTANAL® analytical standard designed for precise and reliable HPLC and GC quantification of chlorpyrifos degradation products, environmental contaminants, and organophosphorus metabolites. As the major hydrolysis and microbial degradation product of chlorpyrifos (CP), TCP is widely monitored in soil, sediment, food crops, water, toxicology studies, and environmental fate research.

This standard is supplied neat, with high purity and controlled specification, making it ideal for calibrations, validation studies, quality control, and trace-level residue analysis in environmental and agricultural matrices.
