Pyridine-4-boronic acid (CAS# 1692-15-5) gabatarwa
4-Pyridine boronic acid abu ne na halitta. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na 4-pyridine boronic acid:
inganci:
- Bayyanar: 4-pyridine boronic acid ne mai kauri maras launi.
- Solubility: Mai narkewa a cikin ruwa da abubuwan kaushi na yau da kullun kamar su alcohols, ethers, da ketones.
- Kwanciyar hankali: 4-Pyridine boronic acid yana da kwanciyar hankali a dakin da zafin jiki, amma bazuwar zai iya faruwa a gaban yanayin zafi mai zafi, matsa lamba, ko mai karfi.
Amfani:
- Mai kara kuzari: 4-pyridylboronic acid za a iya amfani dashi azaman mai kara kuzari a cikin halayen haɗin gwiwar kwayoyin halitta, kamar halayen samuwar haɗin CC da halayen iskar shaka.
- Reagent Coordination: Ya ƙunshi zarra na boron, kuma 4-pyridylboronic acid za a iya amfani dashi azaman reagent na haɗin gwiwa don ions ƙarfe, yana taka muhimmiyar rawa a cikin catalysis da sauran halayen sinadarai.
Hanya:
- 4-Pyridine boronic acid za a iya samu ta hanyar amsa 4-pyridone tare da boric acid. Za a daidaita ƙayyadaddun yanayin amsawa bisa ga ainihin halin da ake ciki.
Bayanin Tsaro:
- 4-Pyridine boronic acid wani nau'in kwayoyin halitta ne na gabaɗaya, amma har yanzu ya zama dole a kula da amintaccen mu'amala. Ya kamata a sa gilashin kariya da safar hannu don aiki.
- A guji haɗuwa da fata da shakar ƙura. Idan akwai haɗarin haɗari tare da fata, kurkura nan da nan da ruwa mai yawa.
- A lokacin amfani da ajiya, ya kamata a kula da shi don kauce wa hulɗa tare da oxidants mai karfi da acid mai karfi don kauce wa haifar da halayen haɗari.
- Lokacin zubar da sharar, yakamata a zubar da shi cikin aminci daidai da dokokin gida.
