Taw qhia
2-Bromo-5-fluorobenzoic acid yog cov organic compound. Nws yog dawb crystalline khoom uas yog soluble nyob rau hauv cov organic solvents xws li cawv, ethers, thiab esters ntawm chav tsev kub.
Kev siv 2-bromo-5-fluorobenzoic acid, uas feem ntau yog siv los ua ib qho nruab nrab ntawm cov organic synthesis, muaj qee yam kev siv hauv kev lag luam tshuaj thiab tshuaj tua kab. Nws tuaj yeem siv los ua ke ntau yam organic tebchaw, xws li aromatic ketones, esters, thiab amino acids. Nws kuj tseem siv tau los ua cov khoom siv hluav taws xob organic thiab cov khoom siv lead ua kua hauv cov kua siv lead ua kua.
Muaj ntau txoj hauv kev los npaj 2-bromo-5-fluorobenzoic acid. Ib txoj hauv kev zoo tshaj plaws yog ua kom p-bromobenzoic acid nrog boron pentafluoride kom tau txais cov khoom lag luam. Cov tshuaj tiv thaiv feem ntau yog ua nyob rau hauv ib qho chaw inert thiab tswj los ntawm qhov kub thiab txias thiab lub sij hawm tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb ntawm 2-bromo-5-fluorobenzoic acid: Nws yog cov organic compound nrog qee yam kev phom sij. Kev sib cuag nrog daim tawv nqaij, qhov muag, lossis nqus tau nws cov vapors tuaj yeem ua rau khaus. Yuav tsum tau ceev faj kom tsim nyog thaum tuav thiab siv, xws li hnav hnab looj tes tiv thaiv, tsom iav, thiab cov khoom tiv thaiv ua pa. Kev sib cuag nrog cov tshuaj muaj zog oxidizing thiab muaj zog acids yuav tsum zam kom tsis txhob muaj tshuaj lom neeg. Thaum lub sijhawm khaws cia thiab kev thauj mus los, qhov kub thiab txias yuav tsum tau zam.
