Acetaminophen, scientifically identified by its CAS number 103-90-2 and commonly known as Paracetamol, is a vital compound in the pharmaceutical sector. Its well-established analgesic and antipyretic properties make it a cornerstone ingredient in numerous medications worldwide. Understanding its chemical and physical properties is fundamental for pharmaceutical manufacturers and formulators.

Chemically, Acetaminophen is N-(4-hydroxyphenyl)acetamide. It presents as a white, odorless crystalline powder. Its molecular formula is C8H9NO2, with a molecular weight of approximately 151.16 g/mol. The compound exhibits solubility in hot water and ethanol, which is advantageous for various formulation processes. Its melting point typically ranges from 168-172°C, a key parameter for quality control. These physical characteristics are critical for ensuring consistent performance when it's purchased as Acetaminophen powder in bulk.

The primary applications of Acetaminophen powder in the pharmaceutical industry are its roles as an analgesic (pain reliever) and an antipyretic (fever reducer). It is particularly effective for mild to moderate pain, such as headaches, muscle aches, and arthritis pain. Unlike many non-steroidal anti-inflammatory drugs (NSAIDs), Acetaminophen has minimal anti-inflammatory effects, making it a suitable option for individuals who cannot tolerate NSAIDs or have conditions where inflammation is not the primary concern. This broad applicability ensures a consistent demand for high-quality Acetaminophen powder from reliable suppliers.

As a pharmaceutical intermediate, Acetaminophen also serves as a valuable precursor in the synthesis of other chemical compounds. Its consistent purity, often exceeding 99% when sourced from reputable acetaminophen powder manufacturers, is crucial for the success of these synthesis pathways. Pharmaceutical buyers prioritize suppliers who can provide detailed specifications and certifications, ensuring that the API meets stringent pharmacopeial standards like USP and BP.

In conclusion, Acetaminophen (CAS 103-90-2) is a critical API with a well-defined set of properties that lend themselves to widespread pharmaceutical applications. From pain and fever management to its role as a chemical intermediate, its importance in the industry is undeniable.
