15862-31-4 - Lus Qhia
Qee qhov khoom ntawm qhov sib xyaw no yog raws li hauv qab no:
1. Cov tsos mob: daj ntseg daj rau txiv kab ntxwv-daj crystalline hmoov.
2. Melting Point: nws melting point ntawm 80-86 degrees Celsius.
3. Solubility: Nws tuaj yeem yaj hauv cov kuab tshuaj organic feem ntau, xws li ethanol, methanol, thiab lwm yam. Nws solubility hauv dej kuj tsawg.
Nws muaj qee yam kev siv hauv cov organic synthesis. Nws tuaj yeem siv los ua cov khoom siv raw hauv cov organic synthesis, koom nrog ntau yam tshuaj lom neeg, thiab sib xyaw cov organic sib txawv lossis cov nruab nrab.
Txoj kev npaj calcium feem ntau yog ua los ntawm nucleophilic hloov cov tshuaj tiv thaiv. Ib txoj hauv kev ntawm kev npaj yog los ua 3-bromo-2-nitropyridine nrog cov amino compound los tsim cov khoom xav tau.
Hais txog kev nyab xeeb cov ntaub ntawv, nws yog ib qho organic compound uas yuav muaj qee yam toxicity thiab irritation. Kev ceev faj txog kev nyab xeeb xws li cov hnab looj tes tiv thaiv tshuaj, tsom iav thiab qhov cua yog xav tau thaum tuav thiab siv. Nyob rau tib lub sijhawm, nws yuav tsum tau muab khaws cia rau hauv lub thawv kaw, kom deb ntawm qhov chaw hluav taws kub thiab lwm yam khoom siv hluav taws xob. Nyob rau hauv rooj plaub ntawm txhob txwm sib cuag los yog noj, nrhiav kev kho mob tam sim ntawd. Yuav tsum ua raws li kev coj ua kev nyab xeeb, xws li pov tseg cov khoom seem lossis pov tseg kom raug.
