WebFor the purpose of this document, the expiry period of a reagent solution should be understood as the period of time during which the reagent is stable and can be used for a given type of analysis. It should be noted that the same reagent may be unfit for use for some purposes because it has expired, but still suitable for other purposes. A triflate group is an excellent leaving group used in certain organic reactions such as nucleophilic substitution, Suzuki couplings and Heck reactions. Since alkyl triflates are extremely reactive in SN2 reactions, they must be stored in conditions free of nucleophiles (such as water). The anion owes its stability to resonance stabilization which causes the negative charge to be spread symmetrically over the three oxygen atoms. An additional stabilization is achieved by the trifluor… i choose in tagalogWebBackground Triangular fibrocartilage complex (TFCC) injections can be applied using anatomical landmarks or under the guide of ultrasound (US).
