CAS: 528-45-0
分子式: C7H4N2O6
分子量: 212.12
沸点: 351.93°C (rough estimate)
熔点: 163-166℃
中文名称: 
3,4-二硝基苯甲酸
3,4-二硝基安息香酸
英文名称: 
3,4-dinitrobenzoic acid
3,4-dinitro-benzoic aci
性质描述: 无色或浅黄色针状结晶。熔点165-166℃。易溶于醇、醚及热水,微溶于冷水。味苦,能升华。
生产方法: 由4-氨基-3-硝基甲苯在硫酸存在下与过硫酸钾反应生成3-硝基-4-亚硝基甲苯。再用重铬酸钾氧化得到3,4-二硝基苯甲酸。用此法制备该品的过程与2,5-二硝基苯甲酸完全相同,可参见该条目。
用途: 用作糖的定量分析试剂,也用于有机合成。
