摘要:Method for the detection of glutamine and its analogs are provided by the present disclosure. Also provided are methods for measuring the levels of glutamine and its analogs, including diagnostic methods. Further provided are methods that utilize glutamine analogs for the synthesis of colored pigments and other useful agents. The methods comprise the use of a nonribosomal peptide synthetase (NRPS) under conditions to produce an indigoidine or indigoidine-related pigment.

摘要:A synthesis method of alanyl-glutamine includes the steps of: The N-terminal protected alanine reacts with triphenylphosphine and hexachloroethane in organic solvent to form active ester, the active ester reacts with glutamine in a solution mixture containing organic solvent and aqueous solution of inorganic base, the resultant mixture is acidified with inorganic acid, and then the N-terminal protecting group is removed. In this method, the raw materials are cheap, the synthesis technique is simple, no disposals of separation and purification are needed, the product is easy to be separated and purified, the toxicities of all the reagents used in the course of production are minimal, it is advantageous to environment protection.

摘要:Synthesis of triazole- and/or triazolium-based polymers is disclosed. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising triazole- and/or triazolium-based polymers; and water. The use of the synthesized triazole- and/or triazolium-based polymers in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.

标 题:Polycationic Polymer Or Copolymer Having Different Cation Types For Slurries In Chemical Mechanical Planarization
发明人：LARBIG GREGOR; SHI XIAOBO
权利人:MERCK PATENT GMBH; VERSUM MAT US LLC
摘要:Synthesis of polycationic polymer or copolymer is disclosed. The polycationic polymer or copolymer are formed by at least one first cationic monomer and at least one second cationic monomer wherein the first cationic monomer and the second cationic monomer have different cationic groups; such as imidazolium group and non-imidazolium group. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising polycationic polymer or copolymer; and water are also disclosed. The use of the synthesized polycationic polymer or copolymer in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.
