Hexyl (2,4,5-trichlorophenoxy)acetate, also known as 2,4,5-T, is a synthetic chemical compound that belongs to the family of chlorophenoxy herbicides. It is an ester derivative of 2,4,5-trichlorophenoxyacetic acid, with a hexyl group attached to the phenoxy moiety. hexyl (2,4,5-trichlorophenoxy)acetate was widely used as a selective herbicide to control broadleaf weeds and woody plants in agricultural settings, particularly in combination with other herbicides like 2,4-D. However, due to concerns over its potential health and environmental impacts, including the production of dioxins as by-products and its association with various health issues, the use of 2,4,5-T has been banned or restricted in many countries. The compound's chemical structure and properties make it effective in inhibiting plant growth by mimicking the action of plant hormones, but its legacy as a controversial agricultural chemical remains a subject of ongoing debate and research.

2630-13-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2630-13-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2630-13:
(6*2)+(5*6)+(4*3)+(3*0)+(2*1)+(1*3)=59
59 % 10 = 9
So 2630-13-9 is a valid CAS Registry Number.

Method for synthesizing 1,4-di(difluoro phenoxy methyl) benzene

-

Paragraph 0029; 0032; 0035; 0038; 0041; 0044; 0047; 0051, (2018/11/03)

The invention provides a method for synthesizing 1,4-di(difluoro phenoxy methyl) benzene. The method comprises the following steps: (1) by taking 1,4-di(difluoro methyl) benzene as an initial raw material, and carrying out a free radical substation reaction with chlorine in the presence of a free radical initiator so as to obtain 1,4-di(chlorine difluoro methyl) benzene; (2) without refining of the intermittent, namely the 1,4-di(chlorine difluoro methyl) benzene, directly carrying out a unimolecule free radical nucleophilic substitution reaction on the intermittent with an alkali and phenol in an organic solvent, and carrying out recrystallization on a crude product, thereby obtaining the 1,4-di(difluoro phenoxy methyl) benzene. The method is gentle in reaction condition, and the obtainedproduct is high in both yield and purity and is applicable to large-scale production.

FACILE AND EFFECTIVE METHOD OF PREPARING 1,4-BIS(CHLORODIFLUOROMETHYL)BENZENE

-

Paragraph 0036; 0037; 0038, (2013/05/21)

The present invention relates to a facile method of preparing 1,4-bis(chlorodifluoromethyl)benzene, comprising the steps of: (A) providing a reactant liquid of 1,4-bis(difluoromethyl)benzene; optionally (B) providing a light source for UV radiation; and (C) introducing chlorine gas into the reactant liquid at a temperature of 50-90° C. under a pressure above 1 atm to obtain 1,4-Bis(chlorodifluoromethyl)benzene. The invented facile method can be utilized in a batch process or a continuous process for effective production of 1,4-bis(chlorodifluoromethyl)benzene.

Efficient synthesis of p-bis-(chlorodifluoromethyl)benzene

Dolbier Jr., William R.,Duan, Jian-Xin,Rong, Xiao X.

, p. 1091 - 1093 (2008/02/08)

Selective, high yield partial fluorination of p-bis-(trichloromethyl)benzene to p-bis-(chlorodifluoromethyl)benzene has been accomplished by warming a slurry of the p-bis-(trichloromethyl)benzene in anhydrous HF which also contains a small quantity of inert solvent, such as 1,2-dichloroethane.

Processes for the preparation of octafluoro-[2,2]paracyclophane

-

, (2008/06/13)

Processes are disclosed for the preparation of octafluoro-[2,2]paracyclophane which utilize a low temperature, e.g., less than about 200° C., and a reducing agent comprising titanium to promote the dimerization of dihalo-tetrafluoro-p-xylenes. One suitable reducing agent is prepared by combining TiCl4 with LiAlH4 in an organic solvent.
