Description

Methylxanthine CAS NO 28109-92-4 is a heterocyclic organic compound belonging to the xanthine class, serving as a versatile chemical intermediate and active pharmaceutical ingredient (API) building block. Its core value lies in its role as a key precursor for synthesizing a range of pharmacologically active compounds, including bronchodilators and central nervous system stimulants. This product is essential for manufacturers in the pharmaceutical, agrochemical, and fine chemical industries seeking reliable, high-purity intermediates for research and production.

Application

• Pharmaceutical Synthesis: A critical intermediate in the production of theophylline, caffeine, and other xanthine-derived APIs used as bronchodilators, diuretics, and stimulants.
• Agrochemical Intermediates: Used in the synthesis of certain herbicides and plant growth regulators, leveraging its heterocyclic structure.
• Biochemical Research: Employed as a standard or reference compound in studies involving adenosine receptor antagonism and phosphodiesterase (PDE) inhibition.
• Fine Chemical Production: Serves as a building block for creating complex molecules in specialty chemical manufacturing.
• Cosmetic & Personal Care Ingredients: Potential use in the synthesis of derivatives for topical formulations targeting skin conditions.

Quality Control

Our Methylxanthine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR spectroscopy, to ensure it meets stringent specifications for use in pharmaceutical and fine chemical synthesis. Certificates of Analysis (COA) are provided with every shipment, detailing all test results against agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
