Product Description
Pharmacopeial information for Benzalkonium chloride Basic Information Benzalkonium chloride is one kind of Algaecide, this product is a mixture of dimethylbenzyl hydrocarbon ammonium chloride. According to the calculation of anhydrous material, containing hydrocarbon ammonium salt (C22H40ClN) should be 95.0% ~ 105.0%. Properties This product is white waxy solid or yellow colloid, aqueous solution shows neutral or weakly alkaline reaction, when shaken to produce a lot of foam. It is very soluble in water or ethanol, slightly soluble in ether. Identification of benzalkonium chloride 1, take about 0.2g of this product, add 1mL of sulfuric acid to dissolve, add 0.1g of sodium nitrate, heat on a water bath for 5 minutes, cool, add 10mL of water and zinc powder 0.5g, warm on a water bath for 5 minutes, take 2mL of the supernatant, add 5% sodium nitrite solution 1mL, cool in iced water, and then add 3mL of alkaline β-naphthol test solution, that is, show scarlet red. 2, take the product, add water to dissolve and dilute into a solution containing about 0.5mg per 1mL, according to the UV-visible spectrophotometric method (General 0401), there is a maximum absorption at the wavelengths of 257nm, 262nm and 269nm. 3, take the product 1% aqueous solution of 10mL, add 0.5mL of dilute nitric acid, a white precipitate occurs, filtered, the precipitate can be dissolved in ethanol, the filtrate shows the identification reaction of chloride (General rule 0301). Company information
The company's main import and export products include
(1)Organic Raw Materials:It has a wide range of uses, which can be divided into three aspects: first, it is used as a raw material for the production of polymer chemical products, i.e., monomers for polymerisation reactions; second, it is used as a raw material for other organic chemical industries, including fine chemical products; and third, it is used as a solvent, refrigerant, antifreeze, and gas adsorbent. Basic organic chemical industry is the basis for the development of the production of various organic chemical products, is the main component of the modern industrial structure.
(2)Flavors and Fragrances:Flavour: Flavour is a mixture of a variety of fragrances (sometimes also containing a certain amount of solvent) blended out of a certain aroma, can be used directly for product fragrance, can be widely used in perfumes, cosmetics, shower gels and other daily necessities.
