Fluroxypyr-Meptyl (CAS No.: 81406-37-3) represents the 1-methylheptyl ester derivative of fluroxypyr, a highly selective post-emergence synthetic auxin herbicide belonging to the pyridinecarboxylic acid chemical family. Designed specifically for agricultural formulations demanding high systemic mobility and lipophilic cuticle penetration, Fluroxypyr-Meptyl rapidly hydrolyzes inside plant tissues into active fluroxypyr acid. This active metabolite binds to specific auxin receptors (TIR1/AFB proteins), triggering unregulated cell division, stem elongation, vascular blockage, and rapid tissue necrosis in susceptible broadleaf species.
Fluroxypyr-Meptyl features superior lipophilicity (Log KOW = 4.53 at 20°C) compared to standard salt formulations. This enables ultra-fast cuticular absorption within 1 hour of application, mitigating rainfastness risks significantly. It exhibits low water solubility (0.09 mg/L at 20°C), making it ideal for stable Emulsifiable Concentrates (EC), Microemulsions (ME), and Oil Dispersions (OD).
Specifically engineered to eradicate hard-to-control broadleaf weeds in cereal crops (Wheat, Barley, Oats, Rye), Maize, Pasture, and Non-crop land without inducing phytotoxicity on grass crops.

As global weed resistance against ALS-inhibitors (sulfonylureas) and EPSPS inhibitors (glyphosate) escalates across North America, Europe, and Australia, Fluroxypyr-Meptyl has evolved into a strategic cornerstone for integrated weed management (IWM) programs.
In small grain cereals, Galium aparine and Kochia scoparia biotypes have developed widespread resistance to chlorsulfuron and metsulfuron-methyl. Fluroxypyr-Meptyl operates via Auxin Group 4 pathways, bypassing ALS target site mutations entirely and delivering near 100% eradication efficiency.
To broaden the weed spectrum and prevent resistance, Fluroxypyr-Meptyl exhibits perfect physical and chemical compatibility with complementary chemistry, such as:
Unlike traditional dicamba or high-dose phenoxy herbicides, Fluroxypyr-Meptyl provides an exceptionally forgiving application window in wheat and barley—from the 2-leaf stage (GS 12) up to flag leaf emergence (GS 39)—without causing spike deformities or yield depression under recommended dosages.
Because Fluroxypyr-Meptyl relies on active translocation via the phloem to plant meristems, application under conditions of active plant growth (warm temperatures, adequate soil moisture) maximizes efficacy. When combining with methylated seed oil (MSO) or non-ionic surfactants (NIS), cuticular absorption speed is accelerated by up to 40%.
Supply stability, cost efficiency, and raw material access are decisive factors for global B2B agrochemical procurement. Operating from Shijiazhuang, Hebei Province, our production facilities utilize state-of-the-art continuous flow technologies and automated DCS (Distributed Control Systems) to manufacture premier active ingredients.
The synthesis of Fluroxypyr-Meptyl depends heavily on key chemical intermediates, primarily 4-amino-3,5-dichloro-6-fluoro-2-pyridyloxyacetic acid and 2-octanol (for the meptyl ester moiety). Our strategic backward integration ensures direct contracts for 2,3-dichloro-5-trifluoromethylpyridine derivatives and fluorinating reagents, safeguarding production runs against upstream market volatility.
Environmental compliance is mandatory for sustainable chemical supply. Our chemical park infrastructure incorporates advanced Thermal Oxidizers (RTO) for VOC containment, MVR evaporators for salt recovery, and biological wastewater treatment systems, ensuring 100% adherence to national green manufacturing standards and guaranteeing uninterrupted factory output year-round.
As environmental regulations tighten globally (such as the EU Green Deal and global solvent reductions), R&D in Fluroxypyr chemistry focuses on eco-friendly formulation matrix design and precise drift control.
Developing Polyurea Microcapsule Suspensions (CS) of Fluroxypyr-Meptyl to extend residual activity in soil while reducing volatile off-target drift during aerial and high-pressure tractor boom spray operations.
Phasing out traditional petroleum-derived C9-C10 aromatic solvents in 200g/L EC formulations, replacing them with methylated soybean oil (MSO), fatty acid methyl esters (FAME), and green polar co-solvents to achieve lower ecotoxicity and higher flash points.
Optimizing physical properties (viscosity, droplet spectrum distribution, anti-evaporation additives) for precision agricultural drone applications in East Asia and South America, maximizing spray coverage per hectare.

B2B pricing for technical grade Fluroxypyr-Meptyl and its formulated products is governed by several core macroeconomic and chemical cost factors. Understanding these dynamics empowers international buyers to optimize procurement timing and secure competitive contract pricing.
To secure the best wholesale pricelist and guaranteed factory capacity:
Fluroxypyr acid is the active herbicidal molecule that interacts with plant cell receptors. However, the acid has limited ability to penetrate the waxy leaf cuticle of plants. Fluroxypyr-Meptyl is the lipophilic 1-methylheptyl ester form designed for commercial formulations. It rapidly crosses the plant cuticle upon application and is enzymatic hydrolysed into active fluroxypyr acid inside living plant tissues within hours.
Yes. Fluroxypyr-Meptyl is registered for post-emergence broadleaf control in corn. However, applications should strictly target early crop growth stages (typically up to the 2-6 leaf stage or V4-V5) to prevent leaf rolling or brace root distortion. Avoid tank-mixing with organophosphate insecticides or crop oil concentrates (COC) when spraying corn during sensitive growth phases.
Due to the lipophilic ester structure of Fluroxypyr-Meptyl, it penetrates leaf cuticles very quickly. Under normal conditions with standard tank-mix adjuvants, rainfastness is achieved within 1 hour after spray droplets dry on leaf surfaces.
Every commercial export batch comes with a Certificate of Analysis (COA), Safety Data Sheet (SDS / MSDS in compliance with GHS), and Bill of Lading documentation. For registration clients, we provide 5-batch analysis GLP reports, toxicological study summaries, environmental fate dossiers, and FAO spec validation data.
Fluroxypyr-Meptyl formulations have a shelf life of 2 years when stored in unopened, original UN-approved containers. Keep in cool, dry, well-ventilated storage rooms away from direct sunlight, open flames, food, and animal feed. Avoid storage temperatures dropping below -5°C or exceeding 40°C for extended periods.
Our QA/QC laboratories utilize modern High-Performance Liquid Chromatography (HPLC) and Gas Chromatography-Mass Spectrometry (GC-MS) equipment. Every batch undergoes strict sampling for active content, free acid limits, moisture, and emulsion stability before dispatch, ensuring full compliance with FAO specifications.
