Acephate - Hebei Dongfeng | Pest Control, Agricultural Insecticide

Acephate, also known as Orthene, is a widely used organophosphate insecticide that has been a cornerstone in pest management for decades. This article provides an in-depth analysis of its chemical properties, safety profile, applications, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd.

Chemical Properties and Technical Specifications

Acephate is a solid compound with a melting point of 93°C and a density of 1.35 g/cm³. Its vapor pressure is exceptionally low at 2.26 x 10⁻⁴ Pa (24°C), indicating minimal volatility, which contributes to its stability in agricultural applications. The flash point of 2°C suggests it is flammable under certain conditions, necessitating careful storage at approximately 4°C.

The compound exhibits excellent solubility in water, chloroform, and DMSO, making it highly versatile for formulation. Its pKa of 11.00±0.46 (predicted) indicates it is a weak base, which influences its behavior in different environments. Acephate typically appears as a white to yellow solid, and its water solubility is described as "readily soluble," further enhancing its applicability in aqueous solutions.

Safety and Risk Assessment

Acephate is classified under the GHS07 symbol, indicating it is a hazardous substance with Warning as the signal word. The Hazard statements H302 (harmful if swallowed) and H312 (harmful if in contact with skin) highlight its potential risks to human health. The Hazard Codes Xn (harmful) and F (flammable) further emphasize the need for proper handling.

The UN1648 3/PG 2 classification indicates it is a hazardous material requiring specific transport protocols. The HS Code 29299040 ensures it is categorized under the correct international trade regulations. For detailed safety data, refer to the product page.

Applications in Pest Control

Acephate is a contact and systemic insecticide, effective against a broad spectrum of pests. It is widely used in cotton, ornamentals, forestry, tobacco, fruits, vegetables, and other crops to target sucking and chewing insects such as aphids, armyworms, and thrips. Its moderate persistence and residual systemic activity make it a preferred choice for long-term pest management.

According to the National Institute of Standards and Technology (NIST), chemical safety assessments for pesticides like Acephate are critical for ensuring regulatory compliance and environmental protection. NIST's Chemistry Division provides standardized methods for analyzing pesticide residues, which are essential for monitoring Acephate's impact on ecosystems and human health.
