Abstract

ABSTRAK Kurkumin merupakan senyawa yang potensial untuk dikembangkan. Senyawa analog kurkumin telah banyak disintesis. Senyawa 4–hidroksi–3–klorobenzaldehid merupakan bahan dasar dalam sintesis analog kurkumin dengan substituen –Cl pada inti aromatiknya. Senyawa4–hidroksi–3–klorobenzaldehid telah disintesis melalui reaksi klorinasi antara p–hidroksibenzaldehid dan gas Cl2, kemurnian 4–hidroksi–3–klorobenzaldehid ditentukan berdasarkan jarak lebur, kromatografi lapis tipis dan LC–MS. Identifikasi struktur senyawa hasil sintesis dilakukan dengan teknik spektrometri, meliputi spektramassa (ESI–MS), spektra inframerah (cm-1, KBr), spektra resonansi magnetik inti proton (δ, ppm, DMSO–d6, 1H–NMR, 500 MHz) dan UV–Vis. Reaksi klorinasi p–hidroksibenzaldehid dihasilkan 4–hidroksi–3–klorobenzaldehid yang berbentuk kristal warna kuning, dengan jarak lebur 128,1–130,8ºC. Rendemen rata–rata yang dihasilkan sebesar 51,37 %.Kata kunci: 4–hidroksi–3–klorobenzaldehid, klorinasi, halogenasi
