I-7-Dehydrocholesterol CAS 434-16-2
I-7-i-Dehydrocholesterol yi-crystalline powder emhlophe, i-crystalline powder ekhanyayo etyheli, yodwa kwaye ikhutshwe kwisikhumba sehagu. Inokufunyanwa kwakhona nge-esterification, bromination, ukupheliswa, kunye ne-hydrolysis ye-cholesterol. Indawo yokunyibilika 150-151 ℃ (anhydrous). [α] 20/D-113.6 ° (chloroform). Ukuba sesichengeni emoyeni kuqhelekile kwi-oxidation. I-pharmaceutical intermediate synthesized by saponification reaction ye-7-dehydrocholesterol. I-7-dehydrocholesterol (7-DHC) yi-5,7-conjugated diene sterol kunye ne-precursor ye-cholesterol biosynthesis.

I-7-Dehydrocholesterol isetyenziswa ikakhulu njengento ephakathi ebalulekileyo yokwenziwa kwevithamin D3 kunye nesongezo kwi-skincare, ukukhuselwa kwelanga, kunye nezithambiso. I-7-dehydrocholesterol (i-7-DHC) yi-5,7-conjugated diene sterol kunye ne-precursor ye-cholesterol biosynthesis. Xa evezwe kwimitha ye-ultraviolet B (UVB), inegalelo ekuveliseni ivithamin D3. I-7-dehydrocholesterol ngumgangatho wangaphakathi wokumiselwa kwe-sterols kwaye ikwasetyenziswa njengezinye ii-reagents zaselabhoratri.
Ihlala ipakishwe kwi-25kg / idrum, i-50kg / idrum, kwaye inokwenziwa iphakheji elungiselelwe.
