Grignard Reagents PowerPoint PPT Presentations

Download Free Sample@ https://bit.ly/2SpaOK9 #ChemicalsMarket #MarketAnalysis #Chemicals #ChemicalsAndMaterial Grignard Reagents are a class of organometallic compounds representing a standard formula R-Mg-X, wherein R is an organic group and X is an atom belonging to the halogen group. Grignard chemicals hold a strong negative charge at the carbon atom and therefore are more attracted towards the positively charged molecules and atoms; this makes Grignard reagents highly reactive and useful for various chemical synthesis and catalytic applications. On the basis of the end user, the NAFTA and Europe Grignard Reagents market is segmented into pharmaceuticals, agrochemicals, flavour & fragrance, packaging, and research segments.
