2257-35-4 Usage
General Description
Trichloroacrylic acid, also known as TCAA, is a strong organic acid that is commonly used in a variety of industrial applications. It is a clear, colorless liquid with a pungent odor and is soluble in water, alcohol, and ether. TCAA is often utilized as a raw material in the production of chemicals such as pharmaceuticals, pesticides, and herbicides. Additionally, it is used as a reagent in organic synthesis and as a catalyst in various chemical reactions. Due to its corrosive nature and potential health hazards, TCAA should be handled with caution and proper safety measures in place.
Check Digit Verification of cas no
The CAS Registry Mumber 2257-35-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,5 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2257-35:
(6*2)+(5*2)+(4*5)+(3*7)+(2*3)+(1*5)=74
74 % 10 = 4
So 2257-35-4 is a valid CAS Registry Number.

An easy access to dichloromethyl nitrovinylidene ketones of five-membered heterocycles is presented starting from nitroperchlorobutadiene. These complex ketones are valuable starting materials for novel product structures in versatile reactions such as selective reductions, substitutions to give α-nitroacryl cyanides, fragmentations by means of an alkoxide, as well as ring-cleavage/ring-closure steps by the action of hydrazine. Some of the products show biological activity in crop protection. Georg Thieme Verlag Stuttgart.
