  <class>SmallMolecule</class>
  <description>(S)-azelastine belongs to the benzodiazines, a subclass of diazanaphthalenes within the organic compounds. This organoheterocyclic compound is associated with 14 recorded sources across multiple sectors. Within electrical and electronic equipment, it is found in cell phones, capacitors, batteries, wires and cables, and printed circuit boards, among one other source. It is also present in synthetic textiles, carpets, and rugs within the textiles, leather, and furnishings category.

Additional sources include food packaging in the food, food processing, and cookware sector, as well as medical devices in the healthcare, pharmaceuticals, and veterinary products sector. The compound is further identified in lubricants used in both energy, oil, and gas, as well as industrial manufacturing and chemical processing. Two additional sectors are recorded as sources. Human exposure to (S)-azelastine occurs through three recorded routes: inhalation, oral, and touch.</description>
