Properties
Properties	【外观性状】为白色结晶性粉末。无臭、味微苦，在水中微溶（1.14%, 25℃), 难溶于乙醇。可溶于稀酸或稀碱。 mp289℃ (分解)。等电点5.89。 [α]D+2.8 (5mol/L HCl), [α]D+6.2 (0.5 mol/L NaOH)。长时间光照则着色。与水共热产生少量吲哚，在氢氧化钠、硫酸铜存在下加热，则产生多量吲哚，与酸在暗处加热较稳定，但与其他氨基酸、糖类、醛类共存时加热则极易分解。用酸分解蛋白质时，色氨酸完全分解。【熔点】289-290 °C (dec.)(lit.)【比旋光度】-31.1 º (c=1, H20)【密度】1.34【折射率】-32 ° (C=1, H2O)【储存条件】Store at RT.【溶解度】20% NH3: 0.1 g/mL at 20 °C, clear, colorless【form 】powder【水溶解性】11.4 g/L (25 ºC)【Merck 】14,9797【BRN 】86197
