I-Hazard Class IRRITANT
I-trans-4-Methoxycinnamic Acid (i-CAS: 943-89-5), i-Esters ephuma kwi-trans-4-methoxycinnamic acid i-absorber esebenzayo ye-UV radiation.Iqeshwe kwi-organic synthesis ye-pharmaceutical intermediates, i-synthetic anti-adrenergic drugs esmolol, izithambiso zokufunxa i-ultraviolet.Kwakhona kusetyenziswa njenge-reagent yekhemikhali.
Okwangoku, eyona isetyenziswa ngokuqhelekileyo i-4-Methoxycinnamic Acid i-sunscreen agent yi-p-Methoxycinnamate octyl, elulwelo olungenambala okanye olumthubi olukhanyayo, olunganyibilikiyo emanzini, olunyibilika kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-ethyl acetate, Ayinantlupheko eluswini. , inokhuseleko oluphezulu olusetyenziswayo, kwaye inezinga eliphezulu lokufunxa i-ultraviolet kwindawo ye-UVB, inokuthintela ngokufanelekileyo imitha ye-ultraviolet ye-280-330mm, kwaye inezinga eliphezulu lokufunxa.Yi;inokuthintela ngokufanelekileyo ukubomvu kwesikhumba kunye nokutshiswa lilanga.Okwangoku, le mathiriyeli ekrwada isetyenziswa kakhulu kwizithambiso ezininzi zokukhusela ilanga kumazwe ahlukeneyo.Ifunyenwe ngokusabela kwe-p-Methoxybenzaldehyde kunye ne-Malonic Acid.
I-4-Methoxycinnamic Acid synthesis: Kwi-25-mL, i-flask ephantsi engqukuva, 4-Methoxybenzaldehyde (0.804 mL, 6.61 mmol) (3), i-Malonic Acid (1.75 g, 16.8 mmol), kunye ne-β-Alanine (0.10 g mmol, 1.12 mmol ) zachithwa kwi-pyridine (3.0 mL, 37.1 mmol) kwaye zatshiswa phantsi kwe-reflux imizuzu engama-90.Emva kokupholisa kwiqondo lobushushu begumbi, umxube wokusabela wafakwa kwibhafu yomkhenkce kunye ne-8.0 mL yeHCl egxininisiweyo yongezwa kancinci.Isiphumo semvula emhlophe siqokelelwe ngokucoca nge-vacuum, ihlanjwe ngamanzi abandayo (2 x 10mL) kwaye yomiswe kakuhle.Imveliso yahlaziywa kwi-ethanol epheleleyo (~ 20 mL).
