Azelastine Impurity 14 HCl(CAS: 19869-42-2)

Azelastine Impurity 14 HCl is a hydrochloride salt of an impurity associated with azelastine, an antihistamine used in allergy treatments. It has the chemical formula C15H22N4O2·HCl and is typically a white to off-white solid with a molecular weight of approximately 325.8 g/mol. It is a basic compound with solubility in water and is commonly encountered during the synthesis and quality control of azelastine.

Azelastine Impurity 14 HCl is primarily used in the pharmaceutical industry for the identification and analysis of impurities in azelastine drug substances. It plays a vital role in drug development, quality assurance, and regulatory compliance. Additionally, it is used in research settings to study the purity and stability of antihistamine compounds.

Azelastine Impurity 14 HCl is generally considered safe when handled properly in controlled laboratory environments. However, it may cause mild irritation if inhaled or contacted with skin. Safety precautions include wearing appropriate personal protective equipment (PPE) such as gloves and goggles. It should be stored in a secure location and handled in accordance with standard chemical safety protocols to minimize risks.

Azelastine Impurity 14 HCl should be stored in a cool, dry, and dark place, ideally at temperatures below 25°C. It is sensitive to moisture and light, so it should be kept in a sealed container with desiccant. Proper storage helps maintain its chemical stability and ensures accurate results in analytical testing.
