In global agricultural chemistry, securing a reliable supply of advanced intermediates is key to delivering high-performance crop protection products. CAS No. 272451-61-3—known chemically as 3-iodo-N2-(2-methyl-1-(methylthio)propan-2-yl)-N1-(2-methyl-4-(perfluoropropan-2-yl)phenyl)phthalamide—is a specialized building block used primarily in the production of modern diamide insecticides, including Flubendiamide and related crop protection active ingredients.
Featuring a pre-assembled core that combines fluorinated and halogenated groups, this high-value intermediate allows agrochemical manufacturers to produce targeted, high-efficiency pest control agents efficiently without needing complex late-stage synthetic steps.
Serves as the direct active precursor for advanced diamide insecticides used globally to protect high-value fruit, vegetable, and row crops.
The specific fluorinated and sulfur-containing structures within the molecule give final crop protection products their strong target selectivity, long-lasting field performance, and excellent crop safety profiles.
By supplying the key complex structural framework in a single intermediate, it simplifies downstream processing steps for agrochemical manufacturers.

To ensure smooth, problem-free processing in active ingredient manufacturing, commercial shipments of CAS 272451-61-3 are delivered against standardized quality benchmarks:
| Quality Parameter | Commercial Standard | Commercial Significance |
|---|---|---|
| Purity (HPLC) | Minimum 97.0% – 98.5% | Ensures high reaction yields and limits unwanted side-products in final active ingredient batches. |
| Physical Form | Off-white to pale yellow solid | High-grade solid material designed for easy handling, charging, and storage. |
| Moisture Content | Low moisture (typically below 0.5%) | Prevents material caking and maintains chemical stability during transit and storage. |
| Packaging & Delivery | Sealed moisture-proof drums or bags | Protects product integrity against humidity and environmental exposure during shipping. |
Typically supplied in heavy-duty fiber drums lined with double polyethylene bags or sealed moisture-barrier bags.
Store in cool, dry, well-ventilated warehouse facilities away from direct heat or sunlight (preferably below 25 °C).
Standard industrial dust controls and personal protective equipment (gloves, safety glasses, and dust masks) should be used during bulk handling.
Navigating chemical supply risks requires working with an established primary producer capable of supporting campaign-scale manufacturing without interruption.

To protect customers against regional logistics issues or plant maintenance disruptions, EASTFINE operates two independent manufacturing facilities in Dalian and Heze:
