	&lt;span style=&quot;color: rgb(0, 0, 0); font-family: &amp;quot;Open Sans&amp;quot;, icomoon, sans-serif; font-size: 16px;&quot;&gt;In this study, we present graphene oxide derivatized with cyclopentylamine (GO-d-CP) as a DMSO-compatible liquid crystal alignment medium that is free from any background NMR signal for application in anisotropic NMR. This novel alignment medium facilitates optimal isotropic and anisotropic conditions within a single sample preparation, controlled by sonication, thereby enabling the measurement of anisotropic NMR parameters- residual dipolar couplings (RDC) and residual chemical shift anisotropy (RCSA). GO-d-CP offers several advantages, including ease of synthesis, isolation of solid GO-d-CP as a stable non-hygroscopic material, and maintenance of the anisotropic state stability &amp;gt;30 days, allowing for prolonged and repetitive experiments. Notably, post the analysis it allows for easy recovery of valuable analytes as well as GO-d-CP for reuse, enabling the routine application of anisotropic NMR in structural analysis of small molecules. We demonstrate its efficacy by analyzing the relative stereochemistry of four compounds - estrone, santonin, griseofulvin, and cinmethylin - using anisotropic NMR data.&lt;/span&gt;&lt;/p&gt;
