High-purity reference materials for accurate and reliable residue analysis.

Overview

MCPA, or (4-Chloro-2-methylphenoxy)acetic acid, is a widely used phenoxy herbicide introduced in 1945. It selectively controls broad-leaf weeds in pasture and cereal crops by mimicking the action of the plant growth hormone auxin, leading to uncontrolled growth and eventual death in susceptible plants.

Uses

MCPA is primarily used to control broadleaf weeds such as thistle and dock in cereal crops and pasture. It is selective for plants with broad leaves, including most deciduous trees, while clovers are tolerant at moderate application levels. MCPA is often used in its salt or esterified forms.

Regulatory

MCPA is classified as a restricted use pesticide in the United States. Its use is monitored by the US Geological Survey, which has documented consistent use from 1992 to 2017. The compound is now used almost exclusively in wheat.

Monitoring

Due to its widespread use, MCPA and its metabolites are monitored in various environmental compartments. Studies show that MCPA can form complexes with metal ions, increasing their bioavailability, which is a topic of ongoing research.

Health Impact

MCPA is moderately toxic to mammals and aquatic organisms but relatively less toxic to birds. It can form complexes with metal ions, potentially increasing their bioavailability and toxicity.

Environmental Impact

MCPA is mobile in soil and not strongly adsorbed to soil particles. It has a typical half-life of 24 days in soil, but this can vary based on environmental conditions. MCPA is considered environmentally hazardous due to its potential to affect the mobility and bioavailability of heavy metals like cadmium and lead.

Safety Measure

Proper handling and application procedures should be followed to minimize exposure and environmental impact. Safety data sheets (SDS) should be consulted for detailed safety measures.

Analytical Standards

HPC Standards GmbH provides high-purity reference materials for MCPA, ensuring accurate and reliable residue analysis. Our products are tested according to international quality requirements and meet the highest industrial standards, making them essential for laboratories conducting food and environmental analysis to ensure compliance with regulatory limits.
