In the complex world of chemical synthesis, specific compounds serve as linchpins for creating advanced materials and pharmaceuticals. One such compound is identified by CAS number 55660-58-7, chemically known as the Ammonium Salt of Acetic Acid Anhydride and Phosphoric Acid (1:1), ammonium salt (1:2). This article delves into its fundamental properties and its critical role as a pharmaceutical intermediate, highlighting why sourcing it from reputable chemical suppliers is essential for industry professionals.

Chemical Profile of CAS 55660-58-7

The compound features a molecular formula of C2H5O5P.2H3N and a molecular weight of 157.06. Visually, it is described as a white powder, a common form for many fine chemicals and pharmaceutical intermediates. The stated assay of ≥98.0% signifies a high level of purity, which is a critical attribute for any chemical intended for use in pharmaceutical manufacturing. Impurities, even in small amounts, can lead to unintended side reactions, reduced yields, and potential safety concerns in the final drug product. Therefore, a high assay is a key indicator of quality for this compound.

Primary Application: Pharmaceutical Intermediates

The primary documented application for CAS 55660-58-7 is its use as a pharmaceutical intermediate. Pharmaceutical intermediates are chemical compounds that are produced during the multi-step synthesis of an Active Pharmaceutical Ingredient (API). They are not the final drug substance but are essential precursors that undergo further chemical transformations to yield the desired API. The specific structure of the Ammonium Salt of Acetic Acid Anhydride and Phosphoric Acid likely provides unique reactive functionalities that are valuable in building complex organic molecules common in pharmaceutical chemistry. For R&D scientists and procurement managers in the pharmaceutical sector, securing a consistent and high-quality supply of such intermediates is vital for uninterrupted production and successful drug development.

Handling and Storage Recommendations

Proper handling and storage are crucial for maintaining the integrity of any chemical compound. For CAS 55660-58-7, the recommendation is to store it in a clean, dry, and cool place, shielded from direct sunlight and rain. These conditions help prevent degradation, moisture absorption, and other forms of contamination that could compromise its purity and suitability for pharmaceutical applications. Adhering to these storage guidelines ensures that the chemical remains within its specified parameters until it is used in the manufacturing process.

Procuring from a Trusted Supplier

When looking to buy or purchase this intermediate, it is imperative to partner with a reliable manufacturer or supplier. Companies that specialize in fine chemicals and pharmaceutical intermediates, particularly those based in regions like China, often provide a combination of quality and competitive price. Obtaining detailed product documents, inquiring about batch-to-batch consistency, and understanding the supplier's quality control measures are essential steps. If you are a pharmaceutical company or research institution seeking a dependable source for CAS 55660-58-7, contacting established suppliers for a quote is the next logical step to ensure your supply chain is robust and your project stays on track.
