3-Hydroxy-2-methylpyridine

3-Hydroxy-2-methylpyridine is a pharmaceutical intermediate that can be used in the synthesis of pyrimidines. 3-Hydroxy-2-methylpyridine acts as a corrosion inhibitor, serving as a mixed-type corrosion inhibitor for carbon steel in HCl medium^[1][2]. In Vitro:3-Hydroxy-2-methylpyridine (10^-5-10^-2 M) acts as a mixed-type corrosion inhibitor for carbon steel in 1 M HCl. Its corrosion inhibition efficiency increases with rising concentration (reaching 91.1% at 10^-2 M and 303 K, 95.3% at 10^-2 M and 313 K, and 95.4% at 10^-2 M and 323 K), and shows a slight increase with elevated temperature across all tested concentrations^[2].
3-Hydroxy-2-methylpyridine (10^-5-10^-2 M) reduces the corrosion rate of carbon steel in 1 M HCl in a concentration-dependent manner; the corrosion inhibition efficiency measured by the weight loss method reaches 89.8% at 10^-2 M and 303 K, 92.4% at 10^-2 M and 313 K, and 94.1% at 10^-2 M and 323 K, and the obtained results are highly consistent with those from polarization measurements^[2].
The adsorption behavior of 3-Hydroxy-2-methylpyridine (10^-5-10^-2 M) on carbon steel in a 1 M HCl system shows concentration dependence^[2].
