In the vast landscape of chemical compounds, amino acids represent a fundamental class of molecules with far-reaching implications across multiple industries. DL-Alanine (CAS 302-72-7) is a prominent member of this group, known for its distinct characteristics and extensive utility. This article delves into the essential aspects of DL-Alanine, from its chemical makeup and functional properties to its diverse applications in food, pharmaceuticals, and beyond. For industry professionals, understanding how to effectively source this compound from reliable manufacturers is key to operational success.

DL-Alanine is characterized as a non-essential amino acid and exists as a racemic mixture, meaning it contains equal parts of the L- and D-isomers. It presents as a white crystalline powder, odorless, and possesses a subtly sweet taste. Its molecular formula is C₃H₇NO₂, with a molecular weight of approximately 89.09 g/mol. The melting point is quite high, often decomposing around 289°C. Its solubility in water is moderate. These physical and chemical properties make it suitable for a wide array of industrial processes. When considering a purchase, it's important to verify these specifications with your DL-Alanine supplier.

The applications of DL-Alanine are remarkably diverse. In the food industry, it serves as a popular food additive, contributing sweetness and acting as a flavor enhancer in various products such as seasonings, beverages, and processed foods. Its ability to moderate taste profiles, such as reducing bitterness or saltiness, adds significant value. In the pharmaceutical sector, DL-Alanine is recognized as a pharmaceutical intermediate, essential for the synthesis of certain drugs and used in biochemical research, including diagnostic tests for liver function. It's also finding its way into cosmetic formulations as a moisturizing and skin-conditioning agent. Businesses looking to buy DL-Alanine can explore these varied uses to optimize their product development.

Sourcing DL-Alanine requires careful consideration of supplier credentials and product quality. Manufacturers often provide different grades, including food grade, pharmaceutical grade, and industrial grade, each with specific purity requirements. For industries with stringent regulations, such as food and pharmaceuticals, ensuring that the DL-Alanine meets international standards (USP, BP, EP, FCC) is paramount. Engaging with manufacturers that offer transparency in their production processes and provide comprehensive documentation, like Certificates of Analysis (CoA), is crucial. Companies like NINGBO INNO PHARMCHEM CO.,LTD. position themselves as reliable manufacturers and suppliers, offering competitive pricing for bulk DL-Alanine directly from China.

In conclusion, DL-Alanine is a versatile and valuable amino acid with a broad spectrum of applications. Its unique properties make it indispensable in food, pharmaceuticals, and cosmetics. For businesses aiming to procure DL-Alanine, a strategic approach to sourcing, focusing on quality, compliance, and supplier reliability, is essential. By partnering with established manufacturers, companies can secure a consistent supply of high-purity DL-Alanine to support their manufacturing and product development needs.
