Phenylboronic acid or benzeneboronic acid, abbreviated as PhB(OH) 2 where Ph is the phenyl group C 6 H 5 - and B(OH) 2 is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Phenylboronic acid is a white powder and is commonly used in organic synthesis.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
a signal word – either Danger or Warning – where necessary; precautionary statements, indicating how the product should be handled to minimize risks to the user (as well as to other people and the general environment) the identity of the supplier (who might be a manufacturer or importer).
4-Formylphenyl boronic acid crystallizes in colorless needles [1] or is obtained as an odorless, whitish powder, which dissolves little in cold but better in hot water. The compound is quite stable [3] and readily forms dimers and cyclic trimeric anhydrides, which complicate purification and tend to protodeboronize, a secondary reaction that occurs frequently in the Suzuki coupling, with ...
Signal word: "Danger" or "Warning" will be used to emphasize hazards and indicate the relative level of severity of the hazard, assigned to a GHS hazard class and category. Some lower level hazard categories do not use signal words. Only one signal word corresponding to the class of the most severe hazard should be used on a label.
The general structure of a boronic acid, where R is a substituent.. A boronic acid is an organic compound related to boric acid (B(OH) 3) in which one of the three hydroxyl groups (−OH) is replaced by an alkyl or aryl group (represented by R in the general formula R−B(OH) 2). [1]
a signal word – either Danger or Warning – where necessary; hazard statements, indicating the nature and degree of the risks posed by the product; the identity of the supplier (who might be a manufacturer or importer) Each precautionary statement is designated a code, starting with the letter P and followed by three digits.
