In the world of chemistry and material sciences, the term "impurities" carries significant weight due to its implications on the purity, efficacy, reliability, and safety of substances. This article aims to demystify the concept of impurities, explore types, delve into how they are defined, and investigate how techniques such as Nuclear Magnetic Resonance (NMR) are employed to detect and analyze these unwanted entities.
Background
Antimicrobial peptide is a kind of antimicrobial peptide found in Bacillus amyloliquefaciens Y2. It has antimicrobial activity.
Halide monomers are halogen-containing organic compounds, including fluorides, chlorides, bromides, iodides, and some interhalogen compounds. It is well known that most of the top halide monomers used in industry are organic halogen compounds, most of which are synthetic products. Currently, more than 15,000 halogenated hydrocarbons are commercially available. Halide monomers have excellent properties such as flame retardancy, easy solubility, and high reactivity.
