HATU is a third-generation uronium salt peptide coupling reagent. HATU increases the rate of peptide coupling reactions, activates amino acids, promotes peptide bond formation in both solution-phase and solid-phase synthesis, and also facilitates peptide assembly, fragment coupling, and linear peptide cyclization. HATU can promote the N-acylation of chitosan to generate amide-linked cationic derivatives with a controllable degree of substitution. HATU is commonly used in amine acylation reactions .

2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) is a metal chelator precursor containing a DOTA macrocyclic structure. DOTA can form highly stable complexes with metal ions (such as 68Ga, 177Lu) through four nitrogen atoms and four carboxylic acid groups to mediate targeted delivery of radionuclides. The tert-butyl ester group (tBu ester) of 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) also protects the carboxylic acid group during synthesis, and forms a free carboxyl group after deprotection reaction for coupling with targeting molecules (such as antibodies, peptides). 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) may be combined with tumor pre-targeting systems through bioorthogonal reactions (such as reverse electron demand Diels-Alder reaction) to study radioactive imaging or therapy of tumor tissues, and is mainly used in tumor pre-targeting research in the field of nuclear medicine .

HBTU (N-HBTU) is a guanidinium-based peptide coupling reagent and immunological sensitizer. HBTU can be used in combination with bases such as DIPEA (HY-130142) to complete coupling reactions, with HOBt and TMU as by-products. HBTU is a standard reagent in automated solid-phase peptide synthesis, particularly for the Fmoc/tBu strategy, which effectively promotes coupling steps, but it is not suitable for sterically hindered amino acids or dipeptide derivatives. HBTU can induce rhinitis, dermatitis, bronchial asthma and severe allergic reactions. HBTU can be used to study the pathogenesis of allergic reactions, occupational rhinitis, allergic contact dermatitis and bronchial asthma .
