CDMT CAS 3140-73-6 2-Chloro-4,6-Dimethoxy-1,3,5-Triazine Maʻemaʻe >99.0% (HPLC)

1. Pono: ʻO kēia huahana he pauka crystalline keʻokeʻo.
2. Hoʻoholo maʻiʻo:
2.1 Nā mea hana a me nā reagents: LC-10AVP Liquid Chromatograph, SPD-10AVP detector, Acetonitrile (chromatographic pure)
ʻO ka waikona Trifluoroacetic (AR)
2.2 Ke Kaʻina Hana: E like me ka hana kiʻekiʻe wai chromatography (Chinese Pharmacopoeia 2010 edition Appendix VI D) hoʻoholo.
2.3 Nā kūlana Chromatographic: ua hoʻohana ʻia ka octadecylsilane bonded silica gel i mea hoʻopihapiha (250 * 4.6mm * 5.0u);Me ka acetonitrile:
ʻO ka wai = 60:40 (PH=2.5 i hoʻoponopono ʻia e ka trifluoroacetic acid) ʻo ia ka pae kelepona.ʻO 240nm ka lōʻihi nalu.Ka wela o ke kolamu: 25;kahe
Ka wikiwiki: 1.0ml / min;ʻAʻole pono ka helu o nā papa theoretical ma lalo o 2000 e like me ka piko nui o CDMT.
2.4 Ke ʻano hoʻoholo: Ua hoʻomākaukau ʻia kēia huahana i loko o kahi hāmeʻa kaʻa kelepona i loaʻa iā CDMT20ug no 1ml e like me ka huahana hoʻāʻo.
ʻO ka hoʻonā.Ua hoʻokomo ʻia ka 10ul o ka hopena hoʻāʻo i loko o ka chromatograph, a ua hoʻopaʻa ʻia ka chromatogram i 2 mau manawa o ka manawa paʻa o ka piko o ka mea nui.
2.5 Nā hualoaʻa: Ua helu ʻia kēia huahana e ke ʻano hana maʻamau a ʻaʻole i emi iho ma lalo o 98.0% CDMT.
3. NMR characterization: alapine (frequency) he 300MHz, me... He mea hoʻoheheʻe, a ua hōʻike ʻia nā laʻana e ka H spectrum NMR ma ka lumi wela.
4. Ana helu hehee:
4.1 Mea hana
YRT-3 kikohoʻe hōʻike mea hoʻoheheʻe helu a me ka capillary no ka hoʻoheheʻe wahi hoʻoholo (i kapa ʻia he capillary).
4.2 Kaʻina hana
E like me ke ʻano o ka hoʻoholo ʻana i ka helu heheʻe (Chinese Pharmacopoeia 2010 edition Appendix VII C).
4.3 Nā hopena
ʻO ka helu hoʻoheheʻe o kēia huahana he 71-78 ℃ (ʻo ka helu he 1.5 ℃ / min).
5. Pohō ma ka maloʻo ʻana:
5.1 Mea hana: ka umu hoʻomaloʻo ʻana i ka ʻōmole palahalaha
5.2 Kaʻina hana: E lawe i 1g o kēia huahana, e kaupaona pololei, e kau iā ia ma 40.0 ℃ a maloʻo i ke kaumaha mau.
5.3 Ka hopena: ʻAʻole ʻoi aku ke kaumaha o ke kaumaha ma mua o 0.5%
5.4 Heluhelu: % = (Ka nui ma mua o ka maloʻo ʻana - ka nui ma hope o ka maloʻo ʻana)/ ka nui ma mua o ka maloʻo ʻana * 100%
6. Waihona: E kūʻai ma kahi maloʻo a maloʻo mai ka mālamalama (≤-20 ℃).
7. Ka manawa nānā hou: hoʻokahi makahiki
