Acephate, also known as Orthene, is a critical organophosphate insecticide widely utilized in agricultural and horticultural practices. This article delves into its chemical properties, technical specifications, applications, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd., while incorporating authoritative references from the National Institute of Standards and Technology (NIST).
Acephate is a contact and systemic insecticide designed to combat a broad spectrum of pests, including aphids, leaf miners, caterpillars, and thrips. Its mechanism of action involves inhibiting acetylcholinesterase (Ache), an enzyme critical to nerve signal transmission in insects. This disruption leads to paralysis and eventual death of the pest. Notably, Acephate is metabolized into methamidophos, a more active compound, but its safety profile for humans and animals is considered favorable due to limited conversion in mammals.
The following table summarizes the key technical parameters of Acephate:
| Property | Details |
|---|---|
| Melting Point | 93°C |
| Density | 1.35 g/cm³ |
| Vapor Pressure | 2.26 × 10⁻⁴ Pa at 24°C |
| Flash Point | 2°C |
| Storage Temperature | Approx. 4°C |
| Solubility | Water, Chloroform, DMSO: Soluble |
| pKa | 11.00 ± 0.46 (Predicted) |
| Form | White to yellow solid |
| Water Solubility | Readily soluble |
Acephate is extensively used in cotton, ornamentals, forestry, tobacco, fruits, vegetables, and other crops to control both sucking and chewing insects. Its systemic activity allows it to be absorbed by plants, providing long-lasting protection against pests such as:
The insecticide's moderate persistence ensures effective pest control without excessive environmental buildup. According to the NIST, proper application of such compounds is critical for balancing agricultural productivity and environmental safety.
Acephate is classified under the GHS07 hazard label, indicating it is a harmful substance. The signal word "Warning" underscores the need for caution during handling. Key safety information includes:
Proper storage at temperatures around 4°C and adherence to safety protocols are essential to mitigate risks. The NIST emphasizes the importance of standardized safety practices in chemical handling, aligning with global regulatory frameworks.

Acephate's role in modern agriculture is pivotal, offering a balance between pest control and environmental sustainability. Its systemic action reduces the need for frequent applications, minimizing ecological impact. However, as highlighted by the NIST, continuous research into safer alternatives and integrated pest management (IPM) strategies is essential to address long-term agricultural challenges.
Acephate remains a cornerstone in the fight against agricultural pests, combining efficacy with a relatively favorable safety profile. Its versatility, supported by Hebei Dongfeng Chemical Technology Co., Ltd.'s comprehensive product range, ensures it meets the diverse needs of global farmers.
