Methyl 4-hydroxybenzoate Methylparaben CAS No.99-76-3
IiNkcazo zeeMveliso
- I-Methyl 4-hydroxybenzoate, ekwabizwa ngokuba yi-Methyl Paraben, isetyenziswa ikakhulu njenge-antiseptic preservative for organic synthesis, ukutya, izinto zokuthambisa, amayeza, kwaye ikwasetyenziswa njengesondlo sokugcina.
- I-Methyl 4-hydroxybenzoate yinto ephilayo. Ngenxa yesakhiwo sayo se-phenolic hydroxyl, inezixhobo ezingcono zokulwa ne-antibacterial kune-benzoic acid kunye ne-sorbic acid. Umsebenzi weparaben ubukhulu becala ngenxa yemo yemolekyuli, kwaye iqela le-hydroxyl kwi-molecule liye laqiniswa kwaye alisekho i-ionized. Ngoko ke, inefuthe elihle kuluhlu lwe-pH 3 ukuya ku-8. Yinto engasebenziyo yeekhemikhali kwaye kulula ukuhambelana nezinto ezahlukeneyo zeekhemikhali.
Uphawu lweMveliso
- Ukusebenza okuzinzileyo;
- Akuyi kubakho ukubola okanye utshintsho lomsebenzi phantsi kobushushu obuphezulu;
- Ihambelana ngokulula nezinto ezahlukeneyo zeekhemikhali;
- Ukusetyenziswa kwezoqoqosho kunye nexesha elide.
