O.; Feringa, B. L.; Helfrich, W.; Szymanski, W.. And the article was published in Chemical Communications (Cambridge, United Kingdom) in 2019. Safety of 4-Bromobutanoic acid The author mentioned the following in the article:
Medical magnetic resonance imaging (MRI) produces high-resolution anatomical images of the human body, but has limited capacity to provide useful mol. information. The light-responsive, liposomal MRI contrast agent described herein could be used to provide an intrinsic theranostic aspect to MRI and enable tracking the distribution and cargo release of drug delivery systems upon light-triggered activation. After reading the article, we found that the author used 4-Bromobutanoic acid(cas: 2623-87-2Safety of 4-Bromobutanoic acid)
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.).Safety of 4-Bromobutanoic acid
