草酰氯是一種農(nóng)藥、醫(yī)藥和涂料等有機(jī)合成的中間體或試劑，農(nóng)藥上可以用于合成磺酰脲素、除草劑芐黃隆、植物生長(zhǎng)調(diào)節(jié)劑等；醫(yī)藥上可以用來(lái)合成頭孢咣莆或頭孢呋辛酯；涂料方面可用于制備甲基丙烯酰異氰酸酯等；在實(shí)驗(yàn)室或工廠上常用來(lái)制備其他酰氯，其用途十分廣泛。
合成方法以草酸為原料，所采用的氯化劑常用氯化亞砜；氯氣/三氯氧磷；五氯化磷或五氯化磷/三氯氧磷等。
工業(yè)草酰氯中三氯氧磷是控制的指標(biāo)之一，浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司，研制氣相色譜法測(cè)定工業(yè)草酰氯中三氯氧磷的新方案，分析效率高，結(jié)果滿意。浩瀚色譜提供完整的分析方法。

Oxaloyl chloride is an intermediate or reagent in organic synthesis of pesticides, pharmaceuticals, and coatings. It can be used in the synthesis of sulfonylureas, herbicides such as bensulfuron, and plant growth regulators; Medically, it can be used to synthesize cefuroxime or cefuroxime axetil; In terms of coatings, it can be used to prepare methacryloyl isocyanates, etc; It is commonly used in laboratories or factories to prepare other acyl chlorides and has a wide range of uses.
The synthesis method uses oxalic acid as the raw material, and the chlorinating agent commonly used is sulfoxide chloride; Chlorine/phosphorus oxychloride; Phosphorus pentachloride or phosphorus pentachloride/phosphorus oxychloride, etc.
One of the control indicators in industrial oxalyl chloride is phosphorus oxychloride. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a new gas chromatography method for the determination of phosphorus oxychloride in industrial oxalyl chloride, which has high analytical efficiency and satisfactory results. Haohan chromatography provides a complete analytical method.
