4,6-Dihydroxypyrimidine

4,6-Dihydroxypyrimidine is used as intermediates of Azoxystrobin. It is also used for production of sulfa drugs, synthetic vitamin B4, and synthetic drugs such as anticancer and auxiliary.

Hydroxypropyl Methylcellulose

Hydroxypropyl methylcellulose is a semisynthetic, inert, viscoelastic polymer used as an ophthalmic lubricant, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products. As a food additive, hydroxypropyl methylcellulose is an emulsifier, thickening and suspending agent, and an alternative to animal gelatin. It is used primarily in construction materials like tile adhesives and renders where it is used as a rheology modifier and water retention agent. Hydroxypropyl methylcellulose solutions were patented as a semisynthetic substitute for tear-film. In addition to its use in ophthalmic liquids, hydroxypropyl methylcellulose has been used as an excipient in oral tablet and capsule formulations, where, depending on the grade, it functions as controlled release agent to delay the release of a medicinal compound into the digestive tract. It is also used as a binder and as a component of tablet coatings. Other applications include paints, cosmetics and detergents.
