Theophylline (CAS 58-55-9) is a well-defined chemical compound with specific physical and chemical properties that dictate its handling, application, and industrial utility. As a fine chemical, its purity, stability, and solubility are critical factors for manufacturers and researchers. Understanding these characteristics, alongside effective sourcing strategies from China, is paramount for optimizing its use. This article provides an overview of Theophylline's properties and its industrial significance.

Physically, Theophylline presents as a white to off-white crystalline powder. It has a high melting point, typically in the range of 270-274°C, indicating its thermal stability as a solid. Its solubility varies across different solvents: it is soluble in water (approximately 8.3 g/l at 20°C), moderately soluble in ethanol, and also dissolves in dilute acids and bases. This solubility profile is important for its formulation in various pharmaceutical preparations and its use in chemical synthesis. The specific Theophylline CAS 58-55-9 uses in industrial processes often depend on these properties.

When sourcing Theophylline, particularly for industrial or large-scale research purposes, partnering with manufacturers in China offers a strategic advantage in terms of cost and volume. Reputable suppliers ensure that the Theophylline they provide meets stringent purity standards, often exceeding 98% as determined by HPLC analysis. Certificates of Analysis (COAs) that detail purity, identification (via FTIR, NMR, Mass Spectrometry), and melting point are essential documents to verify product quality. This diligent approach to sourcing ensures that the Theophylline purchased is suitable for its intended applications.

Industrially, Theophylline serves not only as an active pharmaceutical ingredient (API) for respiratory conditions but also as a crucial fine chemical intermediate. Its purine structure can be modified to synthesize derivatives with potentially improved pharmacological profiles or to create entirely new therapeutic agents. Its consistent availability and relatively competitive price point from Chinese suppliers make it an attractive option for chemical synthesis and drug discovery programs. Companies looking to buy Theophylline for such purposes can benefit from established supply chains.

In conclusion, Theophylline's well-characterized physical and chemical properties, coupled with the availability of high-quality material from Chinese manufacturers, solidify its importance in the chemical and pharmaceutical industries. Whether used directly as a medication or as a versatile fine chemical intermediate, Theophylline plays a significant role in advancing healthcare and scientific knowledge.
