Dicamba Dimethylamine Salt (CAS 2300-66-5) is a chemical compound widely recognized for its role as a selective herbicide. For procurement managers and R&D scientists, a deep understanding of its chemical properties and safety is essential. As a committed manufacturer and supplier of Dicamba Dimethylamine Salt in China, we aim to provide clear, accurate information to facilitate informed purchasing decisions.

Chemical Profile and Properties

Dicamba Dimethylamine Salt is the dimethylamine salt of dicamba acid. The IUPAC name for the acid form is 3,6-dichloro-2-methoxybenzoic acid. The salt form, CAS 2300-66-5, typically appears as a white to brown crystalline solid or powder and has a molecular weight of approximately 266.12 g/mole. It is highly soluble in water, which is a significant advantage for its formulation into liquid herbicide products. Its chemical structure contributes to its function as a synthetic auxin, disrupting plant growth processes. The purity of the compound, often specified at 99%, is a critical factor for its efficacy and safety in application.

Mechanism of Action

Dicamba DMA Salt acts by mimicking natural plant hormones, specifically auxins. At low doses, it can stimulate growth, but at higher concentrations, it causes abnormal and uncontrollable growth patterns in susceptible broadleaf plants. This disruption leads to twisting of leaves and stems, inhibiting photosynthesis and ultimately causing plant death. This targeted mode of action allows for effective weed control while minimizing damage to tolerant crops when used correctly.

Safety Considerations and Regulatory Information

Understanding the safety profile of any chemical is paramount. Dicamba DMA Salt, like many agrochemicals, requires careful handling and adherence to safety guidelines. According to various assessments, Dicamba is classified with varying toxicity levels depending on the exposure route and formulation. For instance:

  • Acute Oral Toxicity: Generally considered moderate, with LD50 values varying by species and formulation.
  • Dermal Toxicity: Typically low, though skin and eye irritation can occur.
  • Inhalation Toxicity: Very low, though irritation can occur with prolonged exposure.

The U.S. EPA has determined that Dicamba is not likely to be a human carcinogen. However, appropriate personal protective equipment (PPE) such as gloves, eye protection, and protective clothing should always be used when handling. Proper ventilation is also recommended. When you buy Dicamba Dimethylamine Salt, always refer to the product’s Safety Data Sheet (SDS) provided by the supplier for comprehensive safety information and handling procedures.
