Amprolium Hydrochloride
Amprolium Hydrochloride is a white, odorless, crystalline powder used primarily as a coccidiostat, which means it inhibits the growth of Eimeria species (protozoan parasites) responsible for coccidiosis in poultry and other animals. It works by mimicking thiamine (vitamin B1), thereby competitively inhibiting thiamine uptake by the parasite, disrupting its metabolism, and preventing its proliferation. Amprolium HCl is widely used in veterinary medicine, especially in poultry farming, and is often included in feed or drinking water. It complies with BP 2008 and USP 32 pharmacopeial standards.
Calcium Hydroxide Hydrated Lime
Calcium Hydroxide Hydrated Lime, commonly known as Hydrated Lime or Slaked Lime, is an inorganic compound with the chemical formula Ca(OH)₂. It appears as a white, odorless, powder or crystalline solid. It is produced by treating quicklime (calcium oxide) with water in a process called slaking. Calcium Hydroxide is moderately soluble in water, forming a strongly alkaline solution known as limewater. It is widely used in construction, environmental, chemical, agricultural, and water treatment applications due to its caustic, neutralizing, and flocculating properties.
