Description

4-bromonaphthalen-2-ol, also known as 4-bromo-2-naphthol, is an organic compound with the molecular formula C10H7BrO. It is a white crystalline solid that is soluble in organic solvents and has a characteristic aromatic smell. 4-bromonaphthalen-2-ol is characterized by the presence of a bromine atom at the 4-position and a hydroxyl group at the 2-position of the naphthalene ring, which imparts unique chemical and physical properties to the molecule.

Uses

Used in Pharmaceutical Industry:
4-bromonaphthalen-2-ol is used as a reactant in the preparation of pyrazoles, which are inhibitors of the macrophage migration inhibitory factor (MIF). MIF is a key regulator of the immune system and has been implicated in various diseases, including autoimmune disorders, cancer, and inflammatory conditions. By inhibiting MIF, pyrazoles can potentially modulate the immune response and offer therapeutic benefits in treating these diseases.
In addition to its application in the pharmaceutical industry, 4-bromonaphthalen-2-ol may also find use in other areas, such as:
1. Chemical Synthesis:
As an intermediate in the synthesis of various organic compounds, including dyes, pigments, and other specialty chemicals.
2. Analytical Chemistry:
As a reference material or standard for the calibration of analytical instruments, such as gas chromatography and mass spectrometry, due to its well-defined chemical structure and properties.
3. Research and Development:
In academic and industrial research settings, 4-bromonaphthalen-2-ol can be used as a building block for the development of new compounds with potential applications in various fields, such as materials science, agrochemistry, and environmental science.

Check Digit Verification of cas no

The CAS Registry Mumber 5498-31-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,9 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5498-31:
(6*5)+(5*4)+(4*9)+(3*8)+(2*3)+(1*1)=117
117 % 10 = 7
So 5498-31-7 is a valid CAS Registry Number.
