Ordering Information

Mechanism of Toxicological Relevance

Organophosphorus pesticides act by:

• Inhibiting acetylcholinesterase (AChE)
• Causing accumulation of acetylcholine in synapses
• Leading to neurotoxicity and cholinergic overstimulation

This makes the mix highly relevant for:

• Toxicology research
• Environmental contamination studies
• Regulatory monitoring programs

Unique Advantages

• High concentration CRM for extended calibration range
• Comprehensive panel of widely regulated organophosphate pesticides
• Manufactured under dual ISO accreditation standards
• Ready-to-use format reduces preparation errors and variability
• Trusted TraceCERT® quality from Sigma-Aldrich

The Sigma-Aldrich™ TraceCERT® Organophosphorus Pesticides Mix A is a premium certified reference material tailored for laboratories performing high-accuracy pesticide residue analysis. Its validated composition, high concentration, and regulatory compliance make it an essential standard for environmental, food safety, and toxicological testing workflows.
