The precision required in chemical synthesis, particularly for pharmaceuticals, places a high demand on the quality and specificity of the raw materials and intermediates used. (R)-3-aminobutanoic acid methyl ester hydrochloride, also referred to by synonyms such as R-3-ABU-OME HCl or CAS 139243-54-2, is a prime example of such a crucial compound. Its chiral nature and functionality make it an indispensable tool for chemists.

This compound is a derivative of the amino acid butanoic acid, specifically the (R)-enantiomer, esterified with methanol and converted into its hydrochloride salt. Typically appearing as a white to off-white solid, its high purity (often 99%+) is a critical factor for its applications. Manufacturers in China, including NINGBO INNO PHARMCHEM CO.,LTD., are key suppliers of this essential intermediate.

In the pharmaceutical industry, the stereochemistry of a molecule is often directly linked to its biological activity. (R)-3-aminobutanoic acid methyl ester hydrochloride provides a ready-made chiral center that can be incorporated into larger, more complex drug molecules. This is vital for developing APIs with targeted therapeutic effects and minimized side effects, as incorrect stereoisomers can be inactive or even harmful. Its role as a pharmaceutical intermediate is thus fundamental to the efficient synthesis of many advanced medicines.

Beyond drug development, this chiral amino ester derivative also finds extensive use as a building block in general organic synthesis. Researchers and chemists leverage its reactive amino and ester groups to construct diverse molecular frameworks. Whether developing new catalysts, functional materials, or complex natural product analogs, the availability of such enantiopure starting materials significantly simplifies synthetic routes and enhances success rates.

When sourcing this compound, consider the advantages of partnering with reputable chemical suppliers in China. Companies like NINGBO INNO PHARMCHEM CO.,LTD. not only provide high-quality materials but also offer competitive pricing and reliable delivery, which are crucial for project timelines and budgets. Understanding the product specifications and adhering to safety guidelines, such as those related to its potential to be harmful if swallowed (H302), ensures safe and effective use.

The consistent availability of high-purity chiral intermediates like (R)-3-aminobutanoic acid methyl ester hydrochloride is a hallmark of advanced chemical manufacturing. For any organization involved in cutting-edge research or production, securing a dependable supply chain for such materials is a strategic imperative.
