General Description
2-(2-thienyl)propionic acid is an organic compound with the chemical formula C8H8O2S. It is also known as tiaprofenic acid and belongs to the class of nonsteroidal anti-inflammatory drugs (NSAIDs). 2-(2-thienyl)propionic acid is used to relieve pain and inflammation caused by arthritis, menstrual cramps, and other conditions. It works by inhibiting the production of certain natural substances in the body that cause inflammation and pain. Tiaprofenic acid is typically administered orally in the form of tablets or capsules, and its effects can be felt within 1-2 hours after ingestion. However, it may cause side effects such as stomach upset, heartburn, and dizziness. It is important to use this medication only as directed by a healthcare professional to minimize the risk of adverse effects.
Check Digit Verification of cas no
The CAS Registry Mumber 54955-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,5 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54955-39:
(7*5)+(6*4)+(5*9)+(4*5)+(3*5)+(2*3)+(1*9)=154
154 % 10 = 4
So 54955-39-4 is a valid CAS Registry Number.

Synthetic process of tiaprofenic acid
-
, (2018/04/01)
The invention relates to a synthetic process of tiaprofenic acid. The synthetic process comprises the following steps: adopting 2-thiotolene as a starting raw material, enabling 2-thiotolene to reactwith trimethylsilyl cyanide to synthesize 2-thiopheneacetonitrile by virtue of bromation, then enabling the 2-thiopheneacetonitrile to react with dimethyl carbonate to be methylated, hydrolyzing cyanogroups, and finally performing F-K reaction with benzoyl chloride, and preparing tiaprofenic acid. The synthetic process has the advantages that the conventional safe raw materials low in price are used for substituting the rare expensive and dangerous raw materials, so that the severe pollution problem is avoided, and the production cost is greatly decreased; and in addition, the process route adopted by the invention is simple, the reaction period is short, the reaction condition is stable, the yield is high and can reach more than 90 percent, the produce obtained after the reaction is highin purity, and the purity can reach more than 99 percent, so that the synthetic process is suitable for the industrialized production.
