2187-88-4 Usage
General Description
1,4,5,8-Naphthalenetetramine, also known as Naphthalenetetramine, is a chemical compound with the molecular formula C10H10N4. It is derived from naphthalene, which is a polycyclic aromatic hydrocarbon often used as an intermediate for other compounds. The tetramine aspect of this compound indicates it contains four amine groups. Like other aromatic amines, it has applications in the production of dyes and polymers. It is not a commonly found compound and its toxicity and environmental effects have not been widely studied.
Check Digit Verification of cas no
The CAS Registry Mumber 2187-88-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,8 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2187-88:
(6*2)+(5*1)+(4*8)+(3*7)+(2*8)+(1*8)=94
94 % 10 = 4
So 2187-88-4 is a valid CAS Registry Number.

Paragraph 0034-0036, (2021/06/02)
The invention discloses a conjugated perimidine corrosion inhibitor and a preparation method thereof. The preparation method comprises the following steps: carrying out acylation and cyclization reaction on 1,4,5,8-tetraminonaphthalene and substituted benzoic acid to obtain dialkyl phenyl perimidine; and 2) performing quaternization reaction on the dialkyl phenyl perimidine and hydrobromic acid to prepare a conjugated perimidine corrosion inhibitor. According to the invention, the conjugated perimidine corrosion inhibitor is high in conjugation degree of molecules, can form a large pi bond to be adsorbed on a metal surface in a planar configuration, is strong in adhesive force, greatly improves the corrosion inhibition rate, can be used as a copper and iron corrosion inhibitor, and has a good corrosion inhibition effect.
