Description

Bepotastine CAS NO 125603-01-2 is a potent, selective histamine H1-receptor antagonist. This compound is a critical active pharmaceutical ingredient (API) valued for its anti-allergic and anti-inflammatory properties. It is primarily required by pharmaceutical manufacturers for the formulation of ophthalmic solutions and oral tablets to treat allergic conjunctivitis and other hypersensitivity disorders.

Application

• Primary Active Pharmaceutical Ingredient (API) in anti-allergic ophthalmic solutions.
• Key component in the formulation of oral tablets for systemic allergy relief.
• Used in clinical research and development of new antihistamine therapies.
• Reference standard in analytical laboratories for quality control and method validation.
• Intermediate in the synthesis of novel pharmaceutical derivatives.
• Essential material for preclinical and pharmacological studies.

Quality Control

Our Bepotastine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical use. A detailed Certificate of Analysis (COA) confirming identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation.
