Heptafluorobutyric anhydride CAS: 336-59-4

Cov tshuaj no paub txog nws lub peev xwm los cuam tshuam nrog ntau pawg ua haujlwm, xws li cawv, amines, thiab acids, los tsim cov volatile derivatives uas tuaj yeem ua rau roj chromatography-mass spectrometry (GC-MS) kev tshuaj xyuas. Heptafluorobutyric anhydride muaj txiaj ntsig zoo hauv kev tshuaj xyuas cov khoom sib xyaw ua ke, xws li cov qauv ib puag ncig, tshuaj, thiab cov kua dej hauv lub cev, qhov twg kev derivatization ntawm cov pab pawg ua haujlwm ua rau muaj kev pom thiab kev daws teeb meem ntawm cov khoom sib xyaw. Nws qhov volatility siab thiab kev ruaj khov ua rau nws yog ib qho cuab yeej muaj txiaj ntsig rau kev tshawb pom thiab kev ntsuas ntawm cov analytes hauv cov concentration ntawm cov kab. Tsis tas li ntawd, heptafluorobutyric anhydride pom cov ntawv thov hauv kev tsim cov tshuaj tshwj xeeb thiab cov tshuaj nruab nrab, qhov twg kev qhia txog cov fluorinated moieties yog qhov xav tau los hloov kho cov khoom ntawm cov organic molecules. Nws cov reactivity tshwj xeeb thiab derivatization muaj peev xwm ua rau nws yog ib qho tseem ceeb reagent hauv kev tshuaj xyuas chemistry, pab txhawb rau kev nce qib ntawm cov txheej txheem tshuaj xyuas thiab kev piav qhia ntawm cov tshuaj sib xyaw ua ke.
