High-purity reference materials for accurate residue analysis

Overview

Parathion-methyl, also known as methyl parathion, is an organophosphate insecticide with the IUPAC name O,O-Dimethyl-O-p-nitrophenylphosphorothioate. It is structurally similar to parathion-ethyl and is used primarily in agricultural settings.

Its chemical formula is (CH₃O)₂P(S)OC₆H₄NO₂, and it appears as a white to tan crystalline solid or powder with a pungent, garlic-like odor.

Uses

Parathion-methyl is used as an insecticide on various crops, including cotton. It is effective in controlling a wide range of insect pests.

Regulatory

Parathion-methyl is classified as Extremely Hazardous (Ia) by the World Health Organization and as Severely Hazardous by the Rotterdam Convention. It is not allowed for sale and import in nearly all countries, with a few exceptions under specified conditions.

Monitoring

Monitoring of parathion-methyl residues is essential for ensuring compliance with regulatory limits. Laboratories conducting food and environmental analysis rely on high-purity reference materials to achieve accurate and reliable results.

Health Impact

Parathion-methyl is an acetylcholinesterase inhibitor, leading to symptoms such as irritated eyes and skin, nausea, vomiting, abdominal pain, diarrhea, salivation, weakness, headache, runny nose, tightness in the chest, blurry vision, pupil constriction, irregular heartbeat, muscle twitches, and difficulty breathing.

Exposure can occur through inhalation, skin contact, ingestion, or eye contact. The National Institute for Occupational Safety and Health (NIOSH) recommends an exposure limit of 0.2 mg/m³ over an 8-hour workday.

Environmental Impact

Parathion-methyl has a low solubility in water (0.006% at 25°C) and a very low vapor pressure (0.00001 mmHg at 20°C). It is reactive with strong oxidizers and water, posing environmental hazards if not managed properly.

Safety Measure

Due to its high toxicity, strict safety measures must be followed when handling parathion-methyl. Personal protective equipment (PPE) such as gloves, masks, and protective clothing is essential to minimize exposure risks.

Analytical Standards

HPC Standards GmbH provides high-purity reference materials for parathion-methyl, ensuring accurate and reliable residue analysis.
