Description
TF-A, also known as Tetrafluoroethylene-Perfluoroalkyl Vinyl Ether Copolymer, is a fluorinated polymer that belongs to the perfluoroalkyl vinyl ether family. It is distinguished by its high chemical resistance, low surface energy, and excellent thermal stability, making it an ideal material for a variety of applications across different industries.
Uses
Used in Cookware Industry:
TF-A is used as a non-stick coating for cookware, providing a durable and easy-to-clean surface that resists food adhesion and makes cooking and cleaning more efficient.
Used in Industrial Applications:
In the industrial sector, TF-A serves as a lubricant, leveraging its low surface energy and chemical resistance to reduce friction and wear in machinery, thereby enhancing the performance and longevity of equipment.
Used in Surface Treatment Industry:
TF-A is utilized as a surface treatment for products that require resistance to water, oil, and/or stains. Its unique properties make it suitable for applications in textiles, automotive, and other industries where surfaces need to maintain their integrity and appearance under challenging conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 134965-85-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,6 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134965-85:
(8*1)+(7*3)+(6*4)+(5*9)+(4*6)+(3*5)+(2*8)+(1*5)=158
158 % 10 = 8
So 134965-85-8 is a valid CAS Registry Number.

Syntheses of pyrrolo2,3-d]pyrimidine 2′,3′- dideoxyribonucleosides related to 2′,3′-dideoxyadenosine and 2′,3′-dideoxyguanosine and inhibitory activity of 5′-triphosphates on HIV-1 reverse transcriptase

The synthesis of 4-chloropyrrolo[2,3-d]pyrimidine a nd 2-amino-4- chloropyrrolo[2,3-d]pyrimidine α-D- and β-D-2′,3′- dideoxyribonucleosides 6a, b and 7a, b is described (Scheme 1). Glycosylation of the pyrrolo[2,3-d]-pyrimidinyl anions of 1a, b with in situ prepared 2,3-dideoxy-α /β-D-glycero-pentofuranosyl chloride (2) was regioselective but afforded anomeric mixtures of the 2′,3′- dideoxyribonucleosides 3a/4a and 3b/4b, respectively. The glycosylation products were deprotected and subjected to nucleophilic displacement yielding various pyrrolo[2,3-d]pyrimidine 2′,3′-deoxyribonucleosides related to 2′,3′-dideoxyadenosine and 2′,3′-dideoxyguanosine. One-pot phosphorylation gave the corresponding triphosphates. Some of them are strong inhibitors of HIV- 1 reverse trauscriptase, similar to corresponding purine 2′,3′-dideoxynucleotides, but exhibit a better selectivity index in comparison to DNA polymerases. According to that, the N(7) of the purine moiety is not an essential binding position of ddATP or ddGTP at the active centre of HIV-1 reverse transcriptase.
