Import 3-Hydroxypyridine-4-Carboxylic Acid — Buy in wholesale FOB from Supplier in United States

3-Hydroxypyridine-4-carboxylic acid (CAS 10128-71-9, molecular formula C6H5NO3) is a heterocyclic fine chemical with a molecular weight of 139.11 g/mol. Supplied by Al Kaza Pharmaceuticals Plc from the United States, this compound is offered at 99%+ purity and functions as a critical intermediate in pharmaceutical and agrochemical synthesis. The material is traded globally in bulk and research quantities, with final specifications dependent on purity grade and order volume.

This pyridine derivative, also known as 3-hydroxy-4-pyridinecarboxylic acid, contains a hydroxyl group at the 3-position and a carboxylic acid at the 4-position on the pyridine ring. The standard synthesis routes for this compound involve controlled oxidation or hydrolysis of substituted pyridine precursors, with typical impurities including unreacted starting materials and positional isomers. Buyers should verify the specific impurity profile, as pharmaceutical applications typically demand residual solvent limits below ICH Q3C guidelines and heavy metal content meeting USP standards.

Primary applications include the synthesis of pyridine-based active pharmaceutical ingredients (APIs), vitamin B3 analogues, and selective herbicide intermediates. The compound is purchased by pharmaceutical manufacturers, custom synthesis houses, and agrochemical formulators. Import buyers should confirm with Al Kaza Pharmaceuticals Plc the exact Certificate of Analysis (CoA) parameters, available packaging formats (typically 1 kg, 25 kg drums, or bulk), and whether the material is stored under inert atmosphere to prevent oxidative degradation.

Al Kaza Pharmaceuticals Plc is a United States-based supplier positioned in the imported supplier tier with a harbor trust designation.
