Abstract
In order to determine the amounts of impurities and to identify the chemical structures of the impurities in the technical product of the plant growth regulator Atonic, the extracts of diethyl ether and dichloromethane were analyzed with GC-FID and GC-MSD. resulting in detection of five impurities and identification of their chemical structures. The amount of the active ingredient atonic in the technical product was about 84% and those of the impurities ranged from 0.24 to 10.74%. The identified impurities in this technical product are 2-methoxyphenol (guaiacol, m/z 124), 2-chloro-6-methoxyphenol and/or 4-chloro-6-methoxyphenol (m/z 158), 1,2-dimethoxy-4-nitrobenzene (m/z 183), and 2,6-bis(1,1-dimethylethyl)-4-methylphenol (m/z 220), suggesting that they are not hazardous impurities.
생장조절제 Atonic 원제 중 부성분의 함량과 화학구조를 구명하기 위하여 diethyl ether와 dichloromethane 분배액을 각각 GC-FID와 GC-MSD로 분석하여 5종 부성분의 화학구조를 구명하였다. 주성분인 Atonic의 함량은 약 84%이었으며, 부성분의 함량은 $0.24\sim10.74%$이었다. 확인된 부성분은 2-methoxy-phenol (guaiacol, m/z 124), 2-chloro-6-methoxyphenol 또는 4-chloro-6-methoxyphenol (m/z 158), 1,2-dimethoxy-4-nitrobenzene (m/z 183), 그리고 2,6-bis(1,1-dimethylethyl)-4-methylphenol (m/z 220)이었으며, 국내에서 규제중인 6종의 유해성분은 포함되지 않은 것으로 판단되었다.
