D. Pradeep. And the article was published in Organic & Biomolecular Chemistry in 2019. COA of Formula: C4H7BrO2 The author mentioned the following in the article:
We have utilized an m-amino benzyl based photoremovable protecting group (PRPG) to develop a new water soluble H2S donor. It efficiently releases H2S on demand in a spatio-temporally controlled fashion by an excited state “”meta effect”” with good chem. and photochem. quantum yield in an aqueous environment. The efficient photorelease of H2S under physiol. conditions was also demonstrated by in vitro studies.4-Bromobutanoic acid(cas: 2623-87-2COA of Formula: C4H7BrO2) was used in this study.
4-Bromobutanoic acid(cas: 2623-87-2) belongs to carboxylic acids. The chief chemical characteristic of the carboxylic acids is their acidity. They are generally more acidic than other organic compounds containing hydroxyl groups but are generally weaker than the familiar mineral acids (e.g., hydrochloric acid, HCl, sulfuric acid, H2SO4, etc.).COA of Formula: C4H7BrO2
