    Ukucaciswa kweMethylparaben

    I-Methylparaben, kunye nenombolo yobhaliso ye-CAS 99-76-3, ikwabizwa ngokuba yiMethyl p-hydroxybenzoate; I-4-(Methoxycarbonyl)phenol.Yeyamacandelo emveliso yoMphuhlisi;IiMathiriyeli eziSebenzayo;iAromatics.Inombolo yayo ye-EINECS ngu-202-785-7.Le fomyula yekhemikhali yi-C.8H8O3kwaye ubunzima bemolekyuli yi-152.15. Ngaphezu koko, igama layo elicwangcisiweyo yi-Benzoic acid, i-4-hydroxy-, i-methyl ester.I-Methylparaben ifunxwa ngokulula kwi-gastrointestinal tract okanye ngesikhumba. I-hydrolyzed kwi-p-hydroxybenzoic acid kwaye ikhutshwe ngokukhawuleza ngaphandle kokuqokelela emzimbeni. Kuluntu olunolusu oluqhelekileyo, i-methylparaben iyinto engabonakaliyo kwaye ingabonakali; nangona kunjalo, ukusabela kwe-aleji kwiiparabens ezityiweyo kuye kwabikwa. Inokufumaneka kwiimveliso ezininzi zesikhumba / ubuso.

    Iimpawu ezibonakalayo malunga neMethylparaben zezi: (1)ACD/LogP: 1.882; (2)# of Rule of 5 Ukwaphulwa: 0; (3)ACD/LogD (pH 5.5): 1.88; (4)ACD/LogD (pH 7.4): 1.83; (5)ACD/BCF (pH 5.5): 15.83; (6)ACD/BCF (pH 7.4): 14.11; (7)ACD/KOC (pH 5.5): 251.25; (8)ACD/KOC (pH 7.4): 223.85; (9)#H abamkeli bond: 3; (10)#H abanikela ngebhondi: 1; (11)#Iibhondi eziJikelezisa ngokukhululekileyo: 3; (12)Isalathiso seRefraction: 1.547; (13)I-Molar Refractivity: 39.908 cm3; (14) Umthamo weMolar: 125.756 cm3; (15) Uxinzelelo lomphezulu: 45.7929992675781 dyne / cm; (16)Ukuxinana: 1.21 g/cm3; (17)INdawo yeFlash: 116.398 °C; (18)I-Enthalpy yoMphunga: 52.377 kJ/mol; (19)Indawo yokuBilisa: 265.536 °C ku-760 mmHg; (20)Uxinzelelo loMphunga: 0.00600000005215406 mmHg kwi-25°C;

    Ukusetyenziswa kwe-Methylparaben: I-Methylparaben yaziwa ngokucotha isantya sokukhula kwe-Drosophila kwinqanaba le-larval kunye ne-pupal. Yi-antifungal esetyenziswa ngokubanzi njengento yokugcina ukutya, iziyobisi, kunye nezinto zokuthambisa. I-Mycocten, kwaye isetyenziswa ngokuqhelekileyo njenge-anti-fungal agent kwi-Drosophila media media.Methylparaben i-anti-fungal agent ehlala isetyenziswa kwiigels zeenwele. Ikhompawundi idla ngokufumaneka kwi-carpules ye-anesthetic yendawo, esebenza njenge-bacteriostatic agent kunye ne-preservative. I-Methylparaben (ekwabizwa ngokuba yi-Nipigin M, i-Tegosept, kunye ne-Mycocten) iqhele ukusetyenziswa njenge-fungicide kwi-Drosophila media media. Ukusetyenziswa kwe-methylparaben kwaziwa ngokucotha isantya sokukhula kwe-Drosophila kwisigaba sombungu kunye ne-pupal.
    I-Methylparaben iyingozi ngokuphefumla, ngokudibana nolusu kwaye ukuba iginyiwe. Iyacaphukisa emehlweni, inkqubo yokuphefumla kunye nolusu .xa uyisebenzisa, nxiba iimpahla ezifanelekileyo zokukhusela, uphephe ukudibana nolusu kunye namehlo. Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango.
