Here, we developed a pencil graphite electrode modified with 3-nitro benzoic acid (PGE/p-NBA) as the sensor material for the determination of resorcinol by employing the differential pulse voltammetric method. The fabricated sensor is utilized to quantify the elevated level of resorcinol in well ...
When alkenes are treated with peroxyacids such asmeta-chloroperoxybenzoic acid (m-CPBA), two new C-O bonds are formed and a C-C pi bond is broken, resulting in the formation of an epoxide. (An O–O bond from m-CPBA is also broken, which is the source of the oxygen in the epoxid...
In an attempt to artificially imitate and stabilize these turns in short acyclic peptides, a series of N-terminally protected pseudopeptides comprising of an α-amino acid and conformationally constrained meta amino benzoic acid (mABA)/meta nitro aniline (mNA) (peptides I–VI) have been ...
It is a conjugate acid of a 3-aminobenzenesulfonate. Production Methods Metanilic acid can be obtained by sulfonation of aniline sulfate with oleum and boric acid at 20 – 50 ℃. The yield is 98%. For industrial production, however, nitrobenzene is sulfonated to m-nitrobenzenesulfonic acid,...
英文: nitro-4-methysulfonyl benzoic acid is synthesized from 4-methysulfonyl toluene by nitration and oxygenation, using sodium dichromate as an oxidizing agent.中文: 本研究以对甲砜基苯甲酸为原料,经硝化、重铬酸钠氧化,制得2硝基4甲砜基苯甲酸,两步反应总收率达80%,产品纯度≥99%。

However, with 1 equivalent of benzoic acid at room temperature, a slow cyclization to the 1,3,5-oxadiazine-2,4(3H)-dione (125; R = Ph) takes place via a Chapman rearrangement (123) → (124) of the 6-benzoyloxy-1,3,5-oxadiazine-2,4(3H)-dione (123; R = Ph) as outlined in...
