Gabatarwa
2-Bromo-5- (trifluoromethyl) pyridine (wanda aka fi sani da BTFP) wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga yanayinsa, amfaninsa, hanyar shiri da bayanin aminci:
inganci:
- Bayyanar: Fari mai ƙarfi
- Nauyin kwayoyin halitta: 206.00 g/mol
- Solubility: BTFP yana da sauƙin narkewa a cikin abubuwan kaushi na halitta (misali, alcohols, ethers, ketones) amma ƙasa mai narkewa cikin ruwa.
Amfani:
- A matsayin tsaka-tsakin haɗin kai: BTFP ana amfani da shi sosai a cikin shirye-shiryen tsaka-tsakin kwayoyin halitta, irin su mahadi na pyridine, mahadi masu ƙanshi, da dai sauransu.
- A matsayin ligand: BTFP za a iya amfani dashi azaman ligand don rukunin ƙarfe kuma yana da hannu a cikin halayen catalytic daban-daban da shirye-shiryen kayan aiki.
- A matsayin reagent: BTFP yana taka muhimmiyar rawa a cikin haɗin gwiwar kwayoyin halitta, kamar haɓakar haɗin gwiwa, amsawar canji, da raguwar amsawa.
Hanya:
2-Bromo-5- (trifluoromethyl) pyridine za a iya haɗa shi ta hanyoyi masu zuwa:
1. Narkar da 2-amino-5- (trifluoromethyl) pyridine a cikin wani kaushi mai dacewa, kamar barasa ko ketone.
2. Add bromine mahadi (misali hydrogen bromide, methyl bromide).
3. Yi amsa a daidai zafin jiki da yanayin motsawa.
4. Tace samfurin kuma aiwatar da crystallization da tsarkakewa.
Bayanin Tsaro:
- BTFP na iya ƙarfafawa ko yin crystallize a ƙananan yanayin zafi, da fatan za a adana a ɗakin zafin jiki kuma ku guje wa crystallization.
- Sanya safar hannu da gilashin kariya masu dacewa yayin aiki don guje wa haɗuwa da fata da idanu.
- Ka guji shakar ƙurarsa ko tururi, saboda BTFP na iya yin tasiri mai ban haushi a kan hanyar numfashi.
- Koma zuwa ƙa'idar aminci mai dacewa lokacin amfani da ko sarrafa BTFP, da zubar da sharar gida da abubuwan kaushi yadda ya kamata.
