HBTU (Hexafluorophosphate Benzotriazole Tetramethyl Uronium) is a coupling reagent used in solid phase peptide synthesis. It was introduced in 1978 and shows resistance against racemization. It was introduced in 1978 and shows resistance against racemization.
HATU was first reported by Louis A. Carpino in 1993 as an efficient means of preparing active esters derived from 1-hydroxy-7-azabenzotriazole (HOAt). [2] HATU is commonly prepared from HOAt and TCFH under basic conditions [3] and can exist as either the uronium salt (O-form) or the less reactive iminium salt (N-form).
Hydroxybenzotriazole (abbreviated HOBt) is an organic compound that is a derivative of benzotriazole.It is a white crystalline powder, which as a commercial product contains some water (~11.7% wt as the HOBt monohydrate crystal).
Consumer Reports (CR), formerly Consumers Union (CU), is an American nonprofit consumer organization dedicated to independent product testing, investigative journalism, consumer-oriented research, public education, and consumer advocacy.
HCTU is an amidinium coupling reagent used in peptide synthesis.It is analogous to HBTU. [1] The HOBt moiety has a chlorine in the 6 position which improves reaction rates and the synthesis of difficult couplings [2] [3] HCTU and related reagents containing the 6-chloro-1-hydroxybenzotriazole moiety can be prepared by reaction with TCFH under basic conditions.

What do the reviews say? It works on tough stains of all kinds. According to countless TikTok posts and over 220,000-plus Amazon ratings, The Pink Stuff works on nearly any surface. "Used it to ...
PyBOP (benzotriazol-1-yloxytripyrrolidinophosphonium hexafluorophosphate) is a reagent used to prepare amides from carboxylic acids and amines in the context of peptide synthesis. [3] It can be prepared from 1-hydroxybenzotriazole and a chlorophosphonium reagent under basic conditions. [ 4 ]
