Polybrominated biphenyl - Wikipedia
Polybrominated biphenyls (PBBs), also called brominated biphenyls or polybromobiphenyls, are a group of manufactured chemicals that consist of polyhalogenated derivatives of a biphenyl core. Their chlorine analogs are the PCBs.
五氟苄基溴-色谱和质谱中的一种通用衍生剂：I.无机阴离子和有机 …
五氟苄基溴（PFB-Br）是一种通用的衍生剂。 几十年来，它被广泛用于色谱和质谱分析中。 溴原子主要是PFB-Br的单个离去基团。 它在水性和非水性体系中被广泛的亲核试剂所取代，在大多数有机溶剂中形成电中性的，在大多数有机溶剂中可溶，通常是热稳定，挥发性，强电子俘获和吸收紫外线的衍生物。 由于这些理化性质的极大优势，PFB-Br成为了一种理想的衍生化试剂，可通过电子捕获检测或在GC-MS中进行电子捕获负离子化学电离后，对包括各种无机和有机阴离子 …
Role of PfbB in adherence of encapsulated and unencapsulated ...
The ability of this bacterium to adhere to epithelial cells is considered as an essential early step in colonization and infection. By screening a whole genome phage display library with sera from...
Perfluorobutanesulfonic acid - Wikipedia
Perfluorobutanesulfonic acid (PFBS) is a PFAS chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of …
Halogen-Bond-Assisted Photoluminescence Modulation in …
2018年9月26日 · Full size image. To confirm that the spectral changes observed are induced by halogen bonding, we repeated the titration experiment with pentafluorobromobenzene (PFBB), a weaker halogen-bond...
Fluorinated Polymers via Para-Fluoro-Thiol and Thiol-Bromo Click …
2020年9月28日 · Herein, the combination of two highly efficient click reactions, namely para-fluoro-thiol click and thiol-bromo substitution reactions, is demonstrated to form fluorinated polymers with tuned hydrophobicity owing to the nature of the dithiol linker compound.
Application of a pentafluorobenzyl bromide derivatization
An analytical method using pentafluorobenzyl bromide (PFBB) derivatization and gas chromatography/mass spectrometry (GC/MS) has been applied to identify and quantify chloro-, bromo- and dichlorophenols in air, water and sediment samples. Phenols in air sample were collected with a PS-2 Sep-PAK cartr ….
Plasminogen- and Fibronectin-binding Protein B Is Involved in the ...
The protein encoded by spr0075, herein referred to as PfbB, is predicted to contain a putative signal peptide, six adjoining repeated regions (each composed of a 150–152-amino acid-long domain), and an LP X TG motif, characteristic of surface proteins that are covalently bound to peptidoglycan (Fig. 1).
Application of a Pentafluorobenzyl Bromide Derivatization
2002年6月19日 · An analytical method using pentafluorobenzyl bromide (PFBB) derivatization and gas chromatography/mass spectrometry (GC/MS) has been applied to identify and quantify chloro-, bromo- and dichlorophenols in air, water and sediment samples.
Plasminogen- and Fibronectin-binding Protein B Is Involved in …
2010年3月5日 · The ability of this bacterium to adhere to epithelial cells is considered as an essential early step in colonization and infection. By screening a whole genome phage display library with sera from infected patients, we previously identified three antigenic fragments matching open reading frame spr0075 of the strain R6 genome.
