Aluminum hydroxide
Aluminum Hydroxide, chemically known as Al(OH)₃, is a white, odorless, and odorless powder or gelatinous substance. It is widely used in pharmaceuticals as an antacid to neutralize stomach acid and relieve indigestion and heartburn. Beyond healthcare, aluminum hydroxide is a crucial component in water purification, fire retardants, and as a precursor or filler in various industrial applications. It functions as a flame retardant by releasing water upon heating, thus cooling the material and diluting flammable gases. Due to its amphoteric nature, it can react both as an acid and base, enhancing its versatility. Aluminum hydroxide is often utilized in manufacturing aluminum salts and in producing aluminum oxide.
Calcium Chloride
Calcium Chloride is an inorganic salt composed of calcium and chlorine with the chemical formula CaCl₂. It typically appears as a white crystalline solid or granular powder, highly soluble in water and exhibiting strong hygroscopic properties. Calcium Chloride is widely used for its moisture-absorbing ability, de-icing, dust control, and as a firming agent in food processing. It finds extensive applications across industrial, pharmaceutical, agricultural, and food sectors due to its efficacy in modifying physical and chemical properties of products and environments.
Calcium Chloride Dihydrate
Calcium Chloride Dihydrate (CaCl₂·2H₂O) is a hydrated form of calcium chloride, appearing as white crystalline granules or flakes containing two molecules of water of crystallization. It is highly soluble in water and exhibits strong hygroscopic and deliquescent properties. This compound is widely used in industrial, pharmaceutical, food, and agricultural sectors due to its moisture absorption, de-icing, dust control, and calcium supplementation capabilities. Compared to anhydrous calcium chloride, the dihydrate form has lower hygroscopicity but is easier to handle and store.
Calcium Nitrite
Calcium Nitrite is an inorganic compound commonly supplied as a white crystalline powder or granules. It serves primarily as a corrosion inhibitor in reinforced concrete structures, protecting steel reinforcement from rust and prolonging structural lifespan. Calcium nitrite is also used in various industrial processes as an oxidizing agent and preservative. Due to its high solubility in water and strong oxidizing properties, it effectively prevents chloride-induced corrosion and improves concrete durability.
Cetirizine Hydrochloride
Cetirizine Hydrochloride is a widely used second-generation antihistamine effective for treating allergic conditions such as allergic rhinitis, chronic urticaria, and other allergy symptoms. It is the hydrochloride salt form of cetirizine, existing as a white to off-white crystalline powder with a slightly bitter taste. Cetirizine HCl acts by selectively blocking peripheral H1 histamine receptors, thereby reducing allergic symptoms without significant sedation or central nervous system depression. It is commonly formulated into tablets, syrups, and capsules as an active pharmaceutical ingredient.
Chloramphenicol Palmitate Micronised
Chloramphenicol Palmitate Micronised is a micronized, lipophilic ester derivative of chloramphenicol, designed for improved solubility and bioavailability compared to the parent drug. It appears as a fine, white to off-white powder with enhanced surface area due to micronization. This antibiotic is widely used for oral formulations, particularly pediatric suspensions, due to its palatability and controlled release properties. Chloramphenicol Palmitate exhibits broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria. Its ester form offers better stability and reduced bitterness, making it a preferred choice in pharmaceutical preparations.
Ferric Chloride Anhydrous
Ferric Chloride Anhydrous (FeCl₃) is a dark brown to black crystalline solid with a metallic luster. It is a highly corrosive, hygroscopic inorganic salt widely used as a chemical reagent, catalyst, and coagulant. In its anhydrous form, ferric chloride is free of water and has a high purity of approximately 98%. It readily dissolves in water, releasing heat and producing acidic solutions. Ferric chloride is valued for its strong Lewis acid properties, making it effective in a variety of industrial, laboratory, and environmental applications. It is commonly supplied as a solid crystalline powder or lumps and should be handled with care due to its corrosive nature.
Zinc Octoate
Zinc Octoate is a metal carboxylate solution containing approximately 10% zinc content, derived from zinc and 2-ethylhexanoic acid (octoic acid). It functions as an effective curing agent, catalyst, and crosslinker in various polymer systems such as paints, coatings, adhesives, and rubber compounds. This compound improves film hardness, drying times, and overall durability of finished products, making it widely used in industrial and manufacturing processes.
