Bromine Liquid Extra Pure

Whatsapp Order

Bromine Liquid Extra Pure is a high-purity, reddish-brown volatile liquid used in advanced laboratory research involving halogenation reactions, redox studies, and analytical chemistry. It serves as a powerful oxidizing and brominating agent in organic synthesis, facilitating the substitution of hydrogen atoms with bromine in a wide range of compounds. In inorganic analysis, it is employed in the preparation of bromide salts and in the determination of unsaturation in oils and fats. Due to its high reactivity and corrosiveness, it is handled under strict safety protocols in fume hoods with appropriate protective equipment. The extra pure grade ensures minimal contamination and consistent reactivity, making it suitable for precise and high-sensitivity applications. It must be stored in tightly sealed, corrosion-resistant containers, away from heat, light, and incompatible materials such as organic solvents and reducing agents.

Barium Hydroxide Hydrate Extra Pure

SHORT DESCRIPTION Barium Hydroxide 8-Hydrate Extra Pure is a high-purity, white crystalline compound containing eight molecules of water of crystallization. It is widely used in laboratory chemistry as a strong base in titration, qualitative analysis, and inorganic synthesis. Its high solubility in water and strong alkalinity make it valuable for neutralization reactions, preparation of barium salts, and as a reagent for detecting sulfates, carbonates, and phosphates. In analytical applications, it is often used where precise pH control and minimal contamination are critical. The extra pure grade ensures consistent performance in high-accuracy experiments. It should be handled with care and stored in a tightly sealed container in a cool, dry place, as it is caustic and sensitive to carbon dioxide in the air, which can lead to carbonate formation.
