In the realm of pharmaceutical development, specific chemical intermediates play pivotal roles in creating effective treatments. Antazoline Hydrochloride (CAS 2508-72-7) is one such crucial compound, widely recognized for its application in ophthalmic formulations as a potent antihistamine. Its ability to act as a histamine H1 receptor antagonist makes it an invaluable ingredient for products targeting eye allergies.

The primary use of Antazoline Hydrochloride in the pharmaceutical industry is to alleviate the symptoms associated with allergic conjunctivitis. This common condition causes discomfort, redness, and itching of the eyes, which are symptoms that Antazoline Hydrochloride effectively counters by blocking the action of histamine. Consequently, it is a key component in many over-the-counter and prescription eye drops designed for rapid relief.

Understanding the chemical properties of Antazoline Hydrochloride is essential for R&D professionals. It is typically supplied as a white to off-white solid, with a melting point of 238°C, a molecular formula of C17H20ClN3, and a molecular weight of 301.81. These specifications, along with its solubility characteristics, are critical for successful formulation design and stability testing. When seeking to purchase this intermediate, engaging with manufacturers who provide detailed Certificates of Analysis is highly recommended.

For pharmaceutical companies, sourcing Antazoline Hydrochloride often involves identifying reliable manufacturers, with many leading suppliers based in China. These manufacturers are equipped to produce the intermediate at scale, adhering to international quality standards. When considering a supplier, it is important to inquire about their production capacity, quality control measures, and pricing for bulk orders. Obtaining price quotes and samples is a standard practice to ensure the material meets the necessary pharmaceutical grade.

The efficacy of Antazoline Hydrochloride in providing targeted relief for eye allergies makes it a cornerstone ingredient for many ophthalmic products. Its role as a first-generation antihistamine, combined with its specific ocular applications, highlights its continued importance in the pharmaceutical market. Collaborating with experienced manufacturers ensures a consistent supply, which is vital for maintaining production schedules and meeting market demand.

In conclusion, Antazoline Hydrochloride is a vital pharmaceutical intermediate for creating effective antihistamine eye treatments. By partnering with reputable manufacturers, particularly those in China known for their quality and capacity, companies can secure a consistent supply of this critical ingredient, thereby supporting the development and production of essential ophthalmic medications.
