![]() ![]() More information about CAS and the CAS registry can be found here. ![]() A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. CAS (Chemical Abstract Service) registry number The EC or list number is the primary substance identifier used by ECHA. ![]() If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. More information about the EC Inventory can be found here. The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). The EC Number is the numerical identifier for substances in the EC Inventory. Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. 529–543.The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. Disinfection, sterilization, and preservation (5th ed.). "Chapter 27: Chemical Sporicidal and Sporostatic Agents". "Antiseptics and disinfectants: activity, action, and resistance". SDS-s can be obtained from the manufacturer and distributor.ġ McDonnell, G Russell, AD (January 1999). The Blogs published on are for resource information only. Always consult the Safety Data Sheet (SDS) when using any chemical including Hydrogen Peroxide. Come visit the biggest Lab Supply showroom in California, or contact us online or at 88. SDS-s can be obtained from the manufacturer and distributor.įor over 40 years, Lab Pro has been committed to delivering a complete chemical inventory including Hydrogen Peroxide for laboratories worldwide. Always consult the Safety Data Sheet (SDS) when using any chemical including Hydrogen Peroxide. Lab Pro having serviced the electronics industry for many years, offers high quality 30% semiconductor grade Hydrogen Peroxide solutions you can trust. Given the special storage conditions of concentrated Hydrogen Peroxide, including explosion hazard, it should only be stored per SDS instructions in vented containers made of glass, stainless steel, aluminum or plastic and in non-combustible storage areas.ģ0% and 35% Hydrogen Peroxide solutions have many applications. Gloves, goggles, face shield and even a gas mask might be recommended, so only experts should handle. Since both grades are oxidizing liquids and are harmful if swallowed, inhaled, or touched, special care must be taken to ensure safe use. A food manufacturer may purchase Hydrogen Peroxide 35% for food processing and aseptic packaging. Alternately a winemaker might use it to neutralize sulfites. Ultratrace analyses also requires ultrapure Hydrogen Peroxide.ģ5% Hydrogen Peroxide might be used by commercial establishments that dilute to 3%. Using any other concentration or grade could cause irreversible damage to expensive equipment. ĭue to the need for smaller and smaller microchips, 30% ultrapure semiconductor grade Hydrogen Peroxide may be required for use in oxidant gas converters to perform ALD, annealing, and interface layer passivation. Bio contamination equipment might also require high quality Hydrogen Peroxide 30%. Using Hydrogen Peroxide 30% can be critical for safely preparing solutions. ![]() From RCA cleaning with CMP slurries of ammonia or HCl to film removal with Piranha solution, it can be used without worry of heavy metal contamination. Since 30% semiconductor grade Hydrogen Peroxide has been the gold standard for electronics manufacturing for years, many preparations, test methods and equipment standards were developed around its use. Although sometimes containing a light stannous stabilizer, semiconductor grade Hydrogen Peroxide is 99.999%+ pure with ultrapure grades being stabilizer-free and having cation impurities in the low ppb-ppt ranges. ![]()
