Unlocking the Answers: Key Questions to Ask When Ordering Tert-Butyl Acetate CAS 540-88-5.

If you are planning on ordering tert-butyl acetate (TBA) CAS 540-88-5, then there are a few key questions that you should consider asking before making your purchase. These questions will help you ensure that you are getting the right product for your needs, at a fair price, and from a reliable supplier.

Question 1: What is the purity of the TBA?

One of the most important questions to ask when ordering TBA is what is the purity of the product. Purity refers to the percentage of the product that is composed of the active ingredient tert-butyl acetate versus any impurities. The higher the purity, the better quality the product will be, and the more effective it will be for your needs.

Question 2: What is the cost of the TBA?

Cost is always a consideration when it comes to ordering any chemical product, and it's important to ask about the price of TBA before making your purchase. You should also ask about any discounts that may be available for bulk orders, as this can save you money in the long run.

Question 3: What is the delivery time for the TBA?

Delivery time is another important factor to consider when ordering TBA, particularly if you need the product to arrive within a certain timeframe. You should ask about the estimated delivery time, as well as any shipping options that are available to ensure that you can get the product when you need it.

Question 4: Do you offer any technical support or advice?

If you are new to working with TBA, then it can be helpful to have access to technical support or advice from the supplier. This can help you ensure that you are using the product safely and effectively, and can also help you troubleshoot any issues that arise during use.

Exclusion of cis-1,1,1,4,4,4-hexafluorobut-2-ene (HFO-mzz-Z)

- EPA added HFO-mzz-Z to the list of compounds excluded from the regulatory definition of volatile organic compounds or VOC. Evidence shows that HFO mzz-Z is negligibly reactive in forming ground-level ozone. This action will allow states to remove regulatory controls on HFO-mzz-Z that are part of State Implementation Plans designed to help meet the ground-level ozone standards. HFO-mzz-Z is used in a variety of applications as a replacement for foam expansion or blowing agents. Learn more

Exclusion of HFE-347pcf2

- EPA added 1,1,2,2-Tetrafluoro-1-(2,2,2-trifluoroethoxy) ethane (also known as HFE-347pcf2; CAS number 406-78-0) to the list of compounds excluded from the regulatory definition of VOC.  Evidence shows that HFE-347pcf2 is negligibly reactive in forming ground-level ozone. This action will allow states to remove regulatory controls on HFE-347pcf2 that are part of State Implementation Plans designed to help meet the ground-level ozone standards. HFE-347pcf2 is used in a variety of applications as a replacement for precision cleaning.  Learn More 81 FR EPA-HQ-OAR-- 2/25/

Remove Requirements for t-Butyl Acetate (TBAC)

- The regulatory definition of VOC excludes t-butyl acetate (also known as tertiary butyl acetate or TBAC; CAS Number: 540-88-5) for purposes of VOC emissions limitations or VOC content requirements on the basis that it makes a negligible contribution to tropospheric ozone formation.  This action removed remaining Clean Air Act volatile organic compound (VOC) requirements for TBAC (e.g., recordkeeping, emissions reporting, photochemical dispersion modeling and inventory requirements) related to the use as a VOC. Learn more. 81 FR EPA-HQ-OAR-- 3/27/ Exclusion of 2-Amino-2-Methyl-1-Propanol - EPA added 2-Amino-2-methyl-1-propanol (also known as AMP, CAS124-68-5) to the list of compounds excluded from the regulatory definition of VOC.  Evidence shows that AMP is negligibly reactive in forming ground-level ozone. This action will allow states to remove regulatory controls on AMP that are part of State Implementation Plans designed to help meet the ground-level ozone standards. AMP is used in a variety of applications for pigment dispersion in water-based coatings such as house paints.  Learn More

Evidence shows that Solstice zd(E) is negligibly reactive in forming ground-level ozone. This action will allow states to remove regulatory controls on Solstice zd(E) that are part of State Implementation Plans designed to help meet the ground-level ozone standards. Solstice zd(E) is used in a variety of applications including as a solvent in aerosol and non-aerosol applications, as a blowing agent in insulating foams for refrigerators/freezers and hot water heaters and as a refrigerant in commercial chillers and waste heat recovery (Rankin cycle) systems.  78 FR EPA-HQ-OAR-- 2/12/ Exclusion of a Group of Four Hydrofluoropolyethers (HFPEs)  EPA added a group of four Hydrofluoropolyethers (HFPEs) to the list of compounds excluded from the regulatory definition of VOC.  Evidence shows that these HFPEs are negligibly reactive in forming ground-level ozone. This action will allow states to remove regulatory controls on the four compounds that are part of State Implementation Plans designed to help meet the ground-level ozone standards.  These compounds are used in a variety of applications as fire suppressants and refrigerants.
