Description

2-Hydroxy-4-(Methylthio)Butyric Acid is a key organic acid derivative containing both a hydroxyl and a methylthio functional group. This compound serves as a vital intermediate and precursor in the synthesis of more complex molecules, particularly in the animal nutrition and pharmaceutical sectors. It is essential for manufacturers and R&D facilities requiring a reliable, high-purity building block for methionine analogs, feed additives, and fine chemical production.

Application

• Animal Feed Additive Precursor: A crucial intermediate in the synthesis of DL-Methionine hydroxy analog (MHA), a widely used methionine source in poultry and livestock nutrition.
• Pharmaceutical Intermediate: Serves as a chiral building block for the synthesis of various active pharmaceutical ingredients (APIs) and therapeutic compounds.
• Fine Chemical Synthesis: Used in organic synthesis for introducing the 4-(methylthio)butyric acid moiety into target molecules for agrochemicals and specialty chemicals.
• Biochemical Research: Employed in metabolic pathway studies and as a standard in analytical laboratories for method development and calibration.
• Cosmetic Ingredients: Potential use as an intermediate in the production of certain specialty surfactants or active ingredients for personal care formulations.

Quality Control

Our 2-Hydroxy-4-(Methylthio)Butyric Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. A Certificate of Analysis (COA) documenting results for assay, related substances, and other critical parameters is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from strong acids and incompatible materials.
