| Description | 2-Methyl-3-hydroxy-5-formylpyridine-4-carboxylate, also known as 5-formyl-3-hydroxy-2-methylpyridine-4-carboxylic acid or 5-formyl-3-hydroxy-2-methylisonicotinate, belongs to the class of organic compounds known as pyridinecarboxylic acids. Pyridinecarboxylic acids are compounds containing a pyridine ring bearing a carboxylic acid group. 2-Methyl-3-hydroxy-5-formylpyridine-4-carboxylate is a moderately basic compound (based on its pKa). In humans, 2-methyl-3-hydroxy-5-formylpyridine-4-carboxylate is involved in the metabolic disorder called the hypophosphatasia pathway. A pyridinemonocarboxylic acid that is pyridine-4-carboxylic acid substituted by a methyl group, hydroxy group and formyl group at positions 2,3 and 5, respectively. |
