121058-85-3 Usage

General Description

2'-O-TBDMS-5'-O-DMT-N4-Ac cytidine is a chemical compound used in the field of organic chemistry. It contains a 2'-O-t-butyldimethylsilyl (TBDMS) protecting group on the 2' hydroxyl group, as well as a 5'-O-4,4'-dimethoxytrityl (DMT) protecting group on the 5' hydroxyl group, and an N4-acetyl (N4-Ac) group on the cytidine base. These protecting groups are used to block certain reactive sites on the cytidine molecule, allowing for selective reactions to occur at other sites. 2'-O-TBDMS-5'-O-DMT-N4-Ac cytidin is commonly used in the synthesis of nucleoside analogs and other nucleic acid derivatives for research and pharmaceutical purposes.

Check Digit Verification of cas no

The CAS Registry Mumber 121058-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,5 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121058-85:
(8*1)+(7*2)+(6*1)+(5*0)+(4*5)+(3*8)+(2*8)+(1*5)=93
93 % 10 = 3
So 121058-85-3 is a valid CAS Registry Number.

An efficient preparation of protected ribonucleosides for phosphoramidite RNA synthesis

Serebryany, Vladimir,Beigelman, Leonid

, p. 1983 - 1985 (2002)

An efficient synthesis of protected ribonucleosides useful for phosphoramidite RNA synthesis is described. Di-t-butylsilylene group was employed for simultaneous protection of 3′- and 5′-hydroxyl functions of nucleoside. Subsequent silylation of free 2′-O

Synthesis of 2'-O-substituted ribonucleosides.

Serebryany,Beigelman

, p. 1007 - 1009 (2007/10/03)

An efficient synthesis of 2'-O-substituted ribonucleosides, including 2'-O-TBDMS and 2'-O-TOM protected as well as 2'-O-Me and 2'-O-allyl derivatives is presented. Di-t-butylsilylene group was employed for simultaneous protection of 3'- and 5'- hydroxyl functions of nucleoside on the first step. Subsequent silylation or alkylation of free 2'-OH followed by introduction of suitable protection on the base moiety and removal of cyclic silyl protection gave target compounds in a high yield.
