Description

4-Hydroxypyridine-3-sulfonic acid is an organic compound that serves as a crucial synthetic intermediate in the pharmaceutical industry. It is characterized by its unique chemical structure, which features a hydroxyl group at the 4-position and a sulfonic acid group at the 3-position of the pyridine ring. 4-Hydroxypyridine-3-sulfonic acid plays a significant role in the synthesis of various pharmaceutical compounds due to its versatile reactivity and functional groups.

Uses

Used in Pharmaceutical Industry:
4-Hydroxypyridine-3-sulfonic acid is used as a synthetic intermediate for the production of 4-methoxy-3-pyridinesulfonyl chloride (M271645). 4-Hydroxypyridine-3-sulfonic acid is a key reactant in the synthesis of (arylpiperazinyl)cyclohexylsulfonamides, which are potential α1-adrenergic receptor antagonists. These antagonists have potential applications in the treatment of various medical conditions, such as hypertension and benign prostatic hyperplasia, by blocking the action of adrenaline on α1-adrenergic receptors.

Check Digit Verification of cas no

The CAS Registry Mumber 51498-37-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,4,9 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51498-37:
(7*5)+(6*1)+(5*4)+(4*9)+(3*8)+(2*3)+(1*7)=134
134 % 10 = 4
So 51498-37-4 is a valid CAS Registry Number.
