Alazzouzi, ElMostafa published the artcileA solid-phase method for the synthesis of small to medium-sized cyclic oligonucleotides, Safety of 3-Chloro-4-hydroxyphenylacetic acid, the publication is Nucleosides & Nucleotides (1997), 16(7-9), 1513-1514, database is CAplus.
Cyclic oligodeoxyribonucleotides (2- to 30-mer) are synthesized by a solid-phase method, for both chain elongation and cyclization, employing a new linker and standard phosphoramidite chem. Fairly pure crude products (>90% by HPLC) are obtained.
Nucleosides & Nucleotides published new progress about 33697-81-3. 33697-81-3 belongs to chlorides-buliding-blocks, auxiliary class Chloride,Carboxylic acid,Benzene,Phenol, name is 3-Chloro-4-hydroxyphenylacetic acid, and the molecular formula is C8H7ClO3, Safety of 3-Chloro-4-hydroxyphenylacetic acid.
