Description

Dodecylammonium (O,p-Dichlorophenoxy)Acetate is a quaternary ammonium salt derived from dodecylamine and the herbicidal acid O,p-dichlorophenoxyacetic acid (a structural analog of 2,4-D). It serves as a highly effective, water-dispersible formulation of the active herbicidal moiety, offering enhanced stability and handling safety compared to the free acid. This compound is widely utilized in industrial agrochemical manufacturing, particularly for the production of selective post-emergent herbicides targeting broadleaf weeds in cereal crops and turf management systems. Formulators, crop protection R&D labs, and contract manufacturing organizations (CMOs) rely on this material for consistent performance and regulatory-compliant synthesis.

Application

• Active ingredient intermediate in the synthesis of selective phenoxy herbicides for agricultural use
• Key component in water-based emulsifiable concentrate (EC) and suspension concentrate (SC) formulations
• Stabilized salt form enabling improved storage stability and reduced volatility versus O,p-dichlorophenoxyacetic acid
• Raw material for controlled-release herbicide granules and coated seed treatments
• Research-grade compound for structure-activity relationship (SAR) studies in plant growth regulator development
• Reference standard in analytical method development and validation for herbicide residue testing (e.g., LC-MS/MS)
• Component in specialty non-agricultural herbicidal products for industrial vegetation management (railways, pipelines, rights-of-way)

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches are tested per internal specifications aligned with ACS Reagent Grade and ISO 9001:2015 quality management requirements. Testing includes identity confirmation (IR spectroscopy), assay (HPLC), heavy metals (ICP-MS), residual solvents (GC), and moisture content (Karl Fischer titration). REACH registration and full regulatory documentation support are provided for global supply.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15–25°C) in a dry, well-ventilated area. Due to its hygroscopic nature, minimize exposure to ambient humidity; use desiccant packs during long-term storage. Avoid contact with strong acids, strong alkalis, and oxidizing agents.
