The pure 5,6- dihydroxyindole is a colorless needle crystal with a melting point of 140℃, which is soluble in hot water but insoluble in petroleum ether. It is stable in crystalline state, but it quickly oxidizes into melanin-like substance in slightly alkaline solution. Because it has little irritation to human skin, it is used to replace commonly used aniline compounds (with carcinogenic, teratogenic and allergic adverse effects) as the active ingredient for blackening in some detergent products. For example, Japan's beauty source hair dye uses it as one of the main active ingredients. It is also a good antioxidant and can be used as an intermediate for the synthesis of some amino acids, alkaloids and tryptamine. In recent years, with the development of new varieties of fine chemicals, the uses of 5,6- dihydroxy flavor are constantly emerging. Many units have carried out the synthesis research of this product, but there is no report of batch supply yet. It is noteworthy that UIV CHEM has successfully broken through the mass production process, and we can provide gram-level to ton-level supply.

It is mainly used for organic intermediates and rust inhibitors. Brand: Soarwin CAS No.: 102-97-6 EC number: 203-067-6 Molecular Formula: C10H15N Density: 0.892 g/mL at 25 °C(lit.) Melting point: 143°C (estimate) Boiling point: 200 °C(lit.) Flash point: 190 °F

It is a cosmetic raw material that can effectively prevent and lighten wrinkles and tighten skin. Relevant experimental studies show that 5PPM palmitoyl tripeptide-1 and 0.05% vitamin A have comparable activities in promoting the synthesizing ability of collagen and glycosaminoglycans, but avoiding their irritation and side reactions. Palmitoyl Tripeptide-1's wrinkle-fighting effect and activity is far superior to that of conventional Vitamin A without any side effects. This makes palmitoyl tripeptide-1 even more advantageous in wrinkle- fighting skin care.

Fuel injectors are located in the intake manifold and spray fuel through a tiny nozzle. The fuel injector uses a special nozzle to spray the fuel as mist, instead of a strong jet stream. When the throttle valve opens, your fuel injector sprays fuel to mix with the air and then enters the engine's combustion cylinders. Maintenance & Usage 1. Before using diesel parts, please carefully wash them in clean diesel. 2. Nozzle is precision pair barrel parts and has been matched in pairs. Never exchange nozzle body with its needle. 3. Nozzle cann't be naked without packaging in air for a long time. 4. After packaging removed and don't use in following days, please put some oil on nozzles to avoid rusting. Part of models

Sulfamic acid Sulfamic acid, also known as amidosulfonic acid, amidosulfuric acid, aminosulfonic acid, and sulfamidic acid, is a molecular compound with the formula H3NSO3. This colorless, water-soluble compound finds many applications. Sulfamic acid melts at 205 °C before decomposing at higher temperatures to water, sulfur trioxide, sulfur dioxide and nitrogen. Sulfamic acid (H3NSO3) may be considered an intermediate compound between sulfuric acid (H2SO4), and sulfamide (H4N2SO2), effectively replacing a hydroxyl (–OH) group with an amine (–NH2) group at each step. This pattern can extend no further in either direction without breaking down the sulfonyl (–SO2–) moiety. Sulfamates are derivatives of sulfamic acid. ●Purity: 99.5%&99.8%Min. ●Molecular formula: NH2SO3H ●Molecular weight: 97.09 Uses: ●Cleaning agent. ●Catalyst for esterification process. ●Dye and pigment manufacturing. ●Herbicide. ●Ingredient in fire extinguishing media. ●Pulp and paper industry as a chloride stabilizer. ●Coagulator for urea-formaldehyde resins. ●Electroplating.
