英文：DBCO-PEG4-acid，DBCO-PEG4-COOH，中文：二苯并环辛炔-四聚乙二醇-羧酸，该试剂所属分类：DBCO PEG  DBCO，CAS编号：1537170-85-6，分子量：552.6，分子式：C30H36N2O8。
DBCO- peg4 -acid是带有PEG连接剂和DBCO基团的DBCO- acid的类似物。DBCO基团由于其应变促进高能，常用于无铜点击化学反应。Hydrophilic polyethylene glycol (peg) chain allows to increase the solubility of water. Terminal carboxylic acids can be in the presence of catalysts (such as EDC or HATU) react with primary amine, forming stable amide bond.德尔塔生物科技其它产品：1,3,4,6-四-O-乙酰基-2-脱氧-2-乙酰氨基-α-D-吡喃葡萄糖，1,3,4,6-tetra-O-acetyl-2-deoxy-2-acetamido-α-D-glucopyranose，CAS：7784-54-51,3,4,6-四-O-乙酰基-2-脱氧-2-乙酰氨基-β-D-吡喃葡萄糖，1,3,4,6-tetra-O-acetyl-2-deoxy-2-acetamido-β-D-glucopyranose，CAS：7772-79-4乙基 2-脱氧-2-邻苯二甲酰亚胺基-1-硫代-β-D-吡喃葡萄糖苷，Ethyl 2-deoxy-2-Phthalimido-β-D-thioglucopyranoside，CAS：130539-43-42-乙酰氨基-3,4,6-三-O-乙酰-2-脱氧-α-D-吡喃葡萄糖酰基氯，3,4,6-Tri-O-acetyl-2-deoxy-2-acetamido-α-D-glucopyranosyl Chloride，CAS：3068-34-6苯基3,4,6-三-氧-乙酰基-2-脱氧-1-硫代-2-(2,2,2-三氯乙氧基甲酰胺基)-β-D-吡喃葡萄糖苷，Phenyl 3,4,6-Tri-O-acetyl-2-deoxy-1-thio-2-(2,2,2-trichloroethoxyformamido)-β-D-glucopyranoside，CAS：187022-49-7该科研试剂的详情分享自 德尔塔生物，由Z整理编辑
