Ferrous Sulfate is a greenish, yellow-brown or white, odorless, crystalline (sand-like) powder. It is used in water treatment and in making other Iron compounds, and as a fertilizer and food additive.
Ferrous metals are hard, heavy, have high density, fragile, not malleable, ductile, magnetic, and rust. Non-ferrous metals are light, malleable, not magnetic, and more expensive. There are different ferrous metals, and each one has its uses. For example, steel is used in buildings, skyscrapers, and structures.
Benzyl Chloride extrapure, 99%, is a high-purity organic compound with the chemical formula C₆H₅CH₂Cl. It is a clear, colorless to slightly yellow liquid with a pungent odor. Benzyl chloride is commonly used in the synthesis of various chemicals such as dyes, perfumes, and pharmaceuticals. Due to its reactive benzyl group, it acts as a key intermediate in producing benzyl compounds. It is highly toxic and corrosive, requiring careful handling and storage in tightly sealed containers under controlled conditions. Its purity of 99% ensures consistent performance in chemical reactions.
Potassium bromide is a white crystalline powder. It is freely soluble in water; it is not soluble in acetonitrile under standard conditions.
Potassium Bromide is used in combination with copper complexes as heat stabilizer in polyamide compounds, where high thermal stability during the product’s life cycle is needed.
Buffer solution, pH 4.0 ± 0.02 is used to establish and maintain an ion activity within narrow range. It is most commonly used to establish hydrogen-ion activity for the calibration of pH meters, in analytical procedures. It is also used to maintain stability of various dosage forms.
Potassium Hydrogen Phthalate Extrapure AR, 99.9% is slightly acidic, and it is often used as a primary standard for acid–base titrations because it is solid and air-stable, making it easy to weigh accurately.
