Rau qhov yuam kev ntawm daim tawv nqaij, ntxuav lub qhov chaw raug mob kom huv si nrog xab npum thiab dej kom tsawg li ntawm tsib caug feeb thiab tshem tawm cov khaub ncaws los yog kab tsho. 2-chloro-5-methylpyrimidine tuaj yeem hlawv ntawm daim tawv nqaij los yog ua rau muaj kev ntxhiab siab. Taug qab mus ntsib tus kws kho mob.
2-chloro-5-methyl pyrimidine yuav tsum muab pov tseg raws li cov khib nyiab tshwj xeeb. Qhov no txhais tau hais tias kev npaj tshwj xeeb yuav tsum tau muab tso rau hauv qhov chaw, siv lub tuam txhab tso cai muab pov tseg rau hauv kev sib txuas nrog nrog koj cov khib nyiab pov tseg hauv zos kom paub meej tias ua raws li cov cai hauv lub tebchaws thiab hauv cheeb tsam. Lub chaw dej num yuav tsum tsis txhob muab tso rau hauv cov dej ntshiab, thiab thaum muaj xuab zeb ntim, muab tshuaj rau hauv lub khob ntim thiab muab pov tseg.
Tshem tawm cov hluav taws kub los ntawm 2-Chloro-5-methylpyrimidine (22536-61-4) combustion ib tug siv tau cov hluav taws kub tua hluav taws qhuav, Cov pa roj carbon atom (IV), polymer ua npuas ncauj los yog cov cawv tiv thaiv cov cawv. Yog tias tsim nyog, ib tug yuav tsum tau siv cov khoom hluav taws kub tiv thaiv thiab tshuab ua pa kom txo tau qhov kev pheej hmoo ntawm kub nyhiab.
Raws li qhov muaj nqis ntawm kev raug xaj ua haujlwm, 2-chloro-5-methylpyramid tsis muaj qhov kev txwv no. General precaution xws li tshuaj fum hoods rau engineers pom zoo thaum lub sij hawm tuav.
