乙酰丙酮铬的产生途径与其化学式中羧酸类，含羟基，含醚键密切相关，该结构特征决定了其在合成/纯化或降解过程中出现的概率与行为。 化学式为 C15H21CrO6 的乙酰丙酮铬（21679-31-2 Chromium acetylacetonate Chromium, tris(2,4-pentanedionato)- (8CI) Chromium, tris(2,4-pentanedionato-O,O')- Chromium(3+), tris(2,4-pentanedionato)- Chromium, tris(2,4-pentanedionato-O,O')-, (OC-6-11)- (9CI) Chromium(III) 4-oxopent-2-ene-2-olate Chromium, tris(2,4-pentanedionato-kappaO2,kappaO4)-, (OC-6-11)- Chromium, tris(2,4-pentanedionato-kappaO,kappaO')-, (OC-6-11)- AI3-60036 CCRIS 3462 Chromic a

应用场景：从实际应用出发，乙酰丙酮铬（CAS 21679-31-2）在化学分析中作为关键的基准对照物质。 推荐以乙酰丙酮铬配制标准系列工作溶液，用于建立标准曲线实现外标法定量。 建议使用甲醇为溶剂配制储备溶液，根据检测灵敏度需求逐级稀释。 使用建议： - 称量前将样品在干燥器内平衡至室温（约30分钟）； - 储备溶液建议用甲醇配制，于室温保存，密封防潮条件下储存； - 低浓度工作液（<10 μg/mL）建议当天配制使用，不宜长期存放； - 开启安瓿瓶/西林瓶后应在干燥环境下尽快使用，防止吸潮影响称量准确性。
