55720-22-4 Usage
General Description
5-Acenaphthenecarboxylic acid is a polycyclic aromatic compound with a carboxylic acid group attached to its structure. It is a white to off-white crystalline solid that is sparingly soluble in water. This chemical is primarily used as an intermediate in the production of dyes, pharmaceuticals, and other organic compounds. It is also used as a corrosion inhibitor, particularly in the oil and gas industry. The acid functionality in 5-Acenaphthenecarboxylic acid allows it to form salts and esters, which can be utilized in various chemical reactions. However, it is important to handle this chemical carefully, as it is considered harmful if swallowed or inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 55720-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,2 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55720-22:
(7*5)+(6*5)+(5*7)+(4*2)+(3*0)+(2*2)+(1*2)=114
114 % 10 = 4
So 55720-22-4 is a valid CAS Registry Number.

Synthesis of aromatic carboxylic acids by carbonylation of aryl halides in the presence of epoxide-modified cobalt carbonyls as catalysts
Boyarskii,Zhesko,Lanina
, p. 1844 - 1848 (2007/10/03)
A new procedure was developed for synthesis of aromatic and heteroaromatic acids and their derivatives (esters, salts) by carbonylation of the corresponding aryl halides. The acids are selectively formed in a high yield under very mild conditions. Highly active catalytic systems, base-containing alcoholic solutions of cobalt carbonyl modified with epoxides, were used to activate aryl halides. 2005 Pleiades Publishing, Inc.
