Dichlorfenidim - Preparation Method
Open Data Verified Data
after mixing with appropriate amount of catalyst anhydrous FeCl3, 3,4-chloronitrobenzene was prepared by chlorine gas chlorination reaction at a certain temperature. The nitro compound was reduced to give 3,4-= chloroaniline. The resulting 3,4-= chloroaniline is added dropwise to a solution of toluene saturated with phosgene and reacted to give 3,4-= phenyl chloroisocyanate. Finally, 3,4-= phenyl chloroisocyanate is reacted with dimethylamine to give trichloron.

Dichlorfenidim - Introduction
This standard substance is mainly used for measuring instrument calibration, analytical method evaluation and quality control, as well as the content determination and residue detection of corresponding components in related fields such as food, hygiene, environment and agriculture. It can also be used for value traceability or as a standard liquid reserve solution. It is diluted step by step and configured into various standard solutions for work. 1. sample preparation This standard substance is made of diuron pure product with accurate purity and fixed value as raw material, chromatographic methanol as solvent, and accurately configured by weight-volume method. Diuron, English name: Diuron,CAS number: 330-54-1 2. traceability and fixed value method This standard substance takes the configuration value as the standard value, and uses high performance liquid chromatography-diode array detector (HPLC-DAD) to compare this batch of standard substances with quality control control samples to verify the preparation value. By using preparation methods, measurement methods and measuring instruments that meet the requirements of metrological characteristics, the traceability of the value of the standard substance is guaranteed. 3. characteristic measure value and uncertainty (see certificate for details) Number name standard value (ug/mL) Relative expansion uncertainty (%)(k = 2)BW10108 The uncertainty of diuron 1003 standard value in methanol is mainly composed of raw material purity, weighing, constant volume, uniformity, stability and other uncertainty components. 4. uniformity test and stability inspection According to the JJF1343-2012 [General Principles and Statistical Principles of Standard Substance Setting], random sampling of sub-packed samples is carried out, uniformity test of solution concentration is carried out, and stability inspection is carried out. The results show that the standard material has good uniformity and stability. The standard substance is valid for 24 months from the date of setting the value. The development unit will continue to monitor the stability of the standard substance. If the value changes are found during the validity period, the user will be notified in time. 5. packaging, transportation and storage, use and precautions 1. Packaging: This standard substance is packed in borosilicate glass ampoules, about 1.2 mL/branch. When removing or diluting, the pipette quantity shall prevail. 2. Transportation and storage: normal temperature transportation, transportation should avoid extrusion and collision; Storage under refrigerated and dark conditions. 3. Use: Balance at room temperature (20±3 ℃) before unsealing, and shake well. Once the ampoule is opened, it should be used immediately and cannot be used as a standard substance after being fused again.

Dichlorfenidim - Application
Open Data Verified Data
substituted urea herbicides, with the role of absorption conduction and a certain Contact killing effect. Plant root or leaf absorption after inhibition of photosynthesis, resulting in loss of green leaves, leaf tip and edge discoloration. At low doses, the herbicide can be selected by the difference and the time difference. At high doses, it becomes a killing herbicide. Mainly used for cotton, soybean, tomato, tobacco, strawberry, grape, Orchard, rubber plantation and other crops to control the annual grass weeds. Such as drought, Horse Tang, green grass, wild amaranth, cyperus, etc.
