氯仿-D（氘氯仿，CDCl3，氘代氯仿）是一种用于NMR（核磁共振）分析的标准纯度溶剂。由于其较高的化学和同位素纯度，在高分辨率核磁共振研究中得到广泛应用。关于氯仿-D在各种有机溶剂中碳-氘伸缩带的红外光谱定量研究已有报道。已有研究针对氯仿-d和液体氯仿的混合物进行了拉曼差分光谱研究，以评估CHCl3 和CDCl3的ν1 和ν2波段频移。
用途
在1H NMR（质子核磁共振）光谱研究中，氘代氯仿被用作溶剂。在31PPNMR（磷-31核磁共振）光谱研究磷酸三苯基和磷酸三(2-氯乙基)过程中，其用作溶剂。在2-(4-溴苄基)-3-羟基丙酸和3-羟基-2-(4-甲氧基苄基)丙酸的1H NMR谱研究中，它也用作氘化溶剂。此外，在3,3′-二羟基-4,4′-二氨基)-二联苯(HAB)和2,2′-双-(3,4-二羧酸)六氟丙烷二酐（6FDA）的1H NMR谱研究中，它也用作氘化溶剂。
Product Introduction
Chloroform-d (Deuterochloroform, CDCl3), deuterated chloroform, is a standard purity solvent for NMR (Nuclear Magnetic Resonance) analyses. It is widely employed in high resolution NMR studies due to its high chemical and isotopic purity. Quantitaive infrared spectral investigations of carbon-deuterium stretching bands of chloroform-d in various organic solvents have been reported. Raman difference spectroscopic studies of mixtures of chloroform-d and liquid chloroform have been conducted to evaluate frequency shifts in the ν1 and ν2 bands of CHCl3 and CDCl3.
Application
Chloroform-d has been employed as solvent in a 1H NMR (Proton Nuclear Magnetic Resonance) spectroscopic study. It has been employed as solvent during the 31PNMR (Phosphorus-31 nuclear magnetic resonance) spectral investigation of triphenyl phosphate and tris(2-chloroethyl) phosphate. It has also been used as the deuterated solvent in the 1H NMR spectral studies of 2-(4-bromobenzyl)-3-hydroxypropanoic acid and 3-hydroxy-2-(4-methoxybenzyl)propanoic acid. It has also been used as the deuterated solvent for the 1HNMR spectral studies of 3,3′-dihydroxy-4,4′-diamino-biphenyl (HAB) and 2,2′-bis-(3,4-dicarboxy-phenyl) hexafluoropropane dianhydride (6FDA) polyimide.
