Desethylene ciprofloxacin is a major metabolite of ciprofloxacin . It is also a degradation product of ciprofloxacin that can be created through advanced oxygenation processes as a potential way to remove ciprofloxacin from wastewater. It is also created during degradation of ciprofloxacin by chlorination.

Carbamazepine 10,11-epoxide 是抗惊厥药卡马西平 (carbamazepine) 的活性代谢物。它由卡马西平通过微粒体中的细胞色素 P450 (CYP) 同种型 CYP3A4 和 CYP2C8 形成，微粒体分别由表达 CYP3A4 或 CYP2C8 的 HepG2 细胞制备。它对小鼠电击诱发的癫痫发作具有抗惊厥活性。

Ibuprofen carboxylic acid is a major metabolite of ibuprofen . It prevents fructose-, cyanate-, and prednisolone-induced inactivation of catalase and fructose- and cyanate-induced inactivation of fumarase when used at a concentration of 2 mM and penetrates into the lens of isolated bovine eyes. Ibuprofen carboxylic acid has been found in bank filtrate and surface water, as well as influent and effluent wastewater, and is considered a micropollutant.

Bromodichloroacetonitrile (BDCAN)是一种主要存在于BDCAN和加工废水中的氮消毒副产物，具有遗传毒性和细胞毒性。

Norfluoxetine-d5 is intended for use as an internal standard for the quantification of norfluoxetine by GC- or LC-MS. Norfluoxetine is an active metabolite of the antidepressant fluoxetine. It is formed from fluoxetine by the cytochrome P450 (CYP) isoforms CYP2C9, CYP2C19, and CYP3A. Norfluoxetine inhibits serotonin (5-HT) uptake in rat brain synaptosomal membrane preparations (Ki = 44.7 nM) and isolated human platelets (IC50 = ~15 nM). It has been found in the tissues of fish exposed to wastewater effluent.

Clofibric acid-d4 is intended for use as an internal standard for the quantification of clofibric acid by GC- or LC-MS. Clofibric acid is a peroxisome proliferator-activated receptor α (PPARα) agonist (EC50 = 50 µM in a transactivation assay) and the active metabolite of clofibrate. It is formed from clofibrate by tissue and serum esterases. Dietary administration of clofibric acid (0.067-0.22%) reduces serum cholesterol, phospholipid, and triglyceride levels in rats. It decreases glutamate oxaloacetate transaminase (GOT) levels and increases glutamate pyruvate transaminase (GPT) and lactate dehydrogenase (LDH) levels, markers of xenobiotic stress, in the plasma of carp (C. carpio) when administered in tank water at a concentration of 10 µg L. Clofibric acid has been found in wastewater effluent.

11(Z),14(Z),17(Z)-Eicosatrienoic acid methyl ester is the ester derivative of 11(Z),14(Z),17(Z)-eicosatrienoic acid, identified within lipid-producing microalgae Nannochloropsis, as well as in diesel-contaminated soils and residential wastewater.

10,11-Dihydro-10,11-dihydroxy Carbamazepine, a metabolite of the anticonvulsant carbamazepine and the antiepileptic prodrug oxcarbazepine, is produced through the biotransformation of carbamazepine via a carbamazepine 10,11-epoxide intermediate by epoxide hydrolase, and from oxcarbazepine via a 10,11-dihydro-10-hydroxy carbamazepine intermediate. This compound has been detected in wastewater effluent, highlighting its environmental presence following pharmaceutical use.

4-Hydroxy Omeprazole sulfide, a metabolite of the proton pump inhibitor omeprazole, has been detected in wastewater effluent.

Carbamazepine-10,11-epoxide-d10 (rings-d10) 是 Carbamazepine-10,11-epoxide 的氘代化合物。Carbamazepine-10,11-epoxide 的 CAS 号为 36507-30-9。Carbamazepine 10,11-epoxide是抗惊厥药卡马西平 (carbamazepine) 的活性代谢物。它由卡马西平通过微粒体中的细胞色素 P450 (CYP) 同种型 CYP3A4 和 CYP2C8 形成，微粒体分别由表达 CYP3A4 或 CYP2C8 的 HepG2 细胞制备。它对小鼠最大电击诱发的癫痫发作具有抗惊厥活性。

Oxalate Oxidase 是一种草酸氧化酶,能在氧气参与下将草酸转化为过氧化氢和二氧化碳.此酶在众多植物(例如大麦)及微生物体内存在,并且可应用于含草酸废水及滤液的处理中.
