- 3-溴甲基苯甲酸甲酯呈白色粉末，可用于配制香精，也用作纤维素酯、纤维素醚、树脂、橡胶等的中间体。
- 制备
在25℃下，向3-溴甲基苯甲酸（1 g，4.6 mmol）在甲醇（20 mL）中的溶液中滴加亚硫酰氯（1.1 g，9.3 mmol）。将反应混合物回流1小时，减压除去甲醇，得到粗粘性物质。粗物质用乙酸乙酯稀释，用水洗涤，用硫酸钠干燥。减压蒸发乙酸乙酯，得到淡黄色油状3-溴甲基苯甲酸甲酯（1.0g，94.0%），产率（1.0 g，94%）。
3-溴甲基苯甲酸甲酯在工业上可用作有机合成中间体、溶剂、香料。具有浓郁的冬青油和尤南迦油香气，用于配制香水香精和人造精油。同时3-溴甲基苯甲酸甲酯也大量用于食品中。此外，其还可以用作纤维素醚、纤维素酯、合成树脂和橡胶的溶剂和聚酯纤维的助染剂。在香料方面多用于人造依兰香料的调合和皂用香精，并用以配制玫瑰型香精。还可在显微分析中作溶剂。
