I found the field of Chemistry very interesting. Saw the article A 4-OTBS benzyl-based protective group for carboxylic acids published in 2019.0. Recommanded Product: 4-Nitrobenzoic acid, Reprint Addresses Xie, HX (corresponding author), East China Univ Sci & Technol, Sch Pharm, Shanghai Key Lab New Drug Design, State Key Lab Bioreactor Engn, Shanghai 200237, Peoples R China.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
Reported herein is a novel 4-OTBS benzyl-based protective group for carboxylic acids. This protective group can be removed in the presence of TBAF or TFA with high efficiency, which makes it compatible with base-sensitive or acid-sensitive substrates. With this protective group, a near-infrared fluorogenic probe for the detection of gamma-glutamyltranspeptidase activities was readily prepared. (C) 2019 Elsevier Ltd. All rights reserved.
