Authentication of 4-chloro-3-methoxy-biphenyl

Authentication of 4-chloro-3-methoxy-biphenyl by 1HNMR, 13CNMR, and GCMS. The purity (>99%) of the compound was determined based on relative peak area by GC-MS.采用质子核磁共振谱（1HNMR）、碳核磁共振谱（13CNMR）以及气相色谱-质谱联用（GC-MS）对4-氯-3-甲氧基联苯（4-chloro-3-methoxy-biphenyl）进行结构确证。该化合物的纯度（>99%）通过气相色谱-质谱联用的相对峰面积法测定。
