Ammonium Acetate
Ammonium acetate is a white crystalline solid or granular powder that is highly soluble in water. It is the ammonium salt of acetic acid and commonly appears as a colorless, odorless compound. Ammonium acetate is widely used in laboratories, chemical synthesis, food industry, pharmaceuticals, and industrial applications due to its buffering capacity and ability to provide both ammonium and acetate ions in solution. It functions as a neutral salt and is valued for its role as a pH buffer, reagent, and stabilizer.
Caustic Soda Flakes (Sodium Hydroxide)
Caustic Soda Flakes, also known as Sodium Hydroxide Flakes (NaOH), are a highly alkaline, white, solid substance that is crystalline and flaky in form. Produced by evaporating aqueous sodium hydroxide solutions, these flakes are highly soluble in water and exhibit strong corrosive properties. Caustic Soda Flakes are widely used in a variety of industrial, chemical, and manufacturing processes due to their strong alkalinity, ability to saponify fats, and effectiveness in pH adjustment. Their high purity and ease of handling in flake form make them suitable for use in chemical synthesis, pulp and paper production, water treatment, and detergent manufacturing.
Caustic Soda Pearls
Caustic Soda Pearls are small, solid, spherical particles of sodium hydroxide (NaOH) produced by a controlled cooling and solidification process. These pearls offer superior flowability, uniform size distribution, and reduced dust generation compared to flake or powder forms. They are highly soluble in water, exhibiting a strong alkaline nature with vigorous exothermic dissolution. Caustic Soda Pearls are widely used across industries including chemical manufacturing, water treatment, pulp and paper processing, and detergents due to their purity, ease of handling, and efficient dissolution characteristics.

Formic Acid (methanoic acid) is the simplest carboxylic acid, typically supplied as an 85% aqueous solution. It is a colorless liquid with a pungent, penetrating odor and strong acidic properties. Formic Acid naturally occurs in insect stings and plant secretions and is widely used in chemical synthesis, agriculture, textile, leather, and rubber industries. The 85% solution balances potency and safe handling for industrial applications. It serves as a preservative, antibacterial agent, and intermediate chemical in numerous manufacturing processes.
Hydrochloric Acid (HCL)
Hydrochloric Acid is a clear, colorless to slightly yellow aqueous solution of hydrogen chloride gas. It is a strong, highly corrosive mineral acid with a sharp, pungent odor. The chemical formula is HCl with a molecular weight of 36.46 g/mol. Hydrochloric Acid is completely miscible with water and many organic solvents. It is non-flammable but extremely corrosive to metals and human tissue. Technical grade Hydrochloric Acid is manufactured for industrial applications including chemical manufacturing, steel pickling, oil well acidizing, water treatment, and pH adjustment. It is available in various concentrations, typically ranging from 30% to 38% by weight.
Iodine Crystals
Iodine Crystals are high-purity elemental iodine in solid crystalline form. These dark violet-black crystals have a characteristic pungent odor and sublime easily at room temperature, releasing violet iodine vapors. Iodine is a halogen element widely used for its antiseptic, oxidizing, and chemical reagent properties in pharmaceutical, industrial, and laboratory applications.
