Terbutaline Impurity D is a synthetic drug with the CAS number 94109-61-2. This product has been developed as an impurity standard for Terbutaline, which is a drug product that has been approved by the United States Pharmacopoeia (USP). Terbutaline Impurity D can be used to study the metabolism of Terbutaline in animals. It is also used to develop new drugs by chemists and other scientists.

Clarithromycin EP Impurity K is an impurity standard for Clarithromycin in the form of a crystalline white powder. It is a synthetic compound which has been used as a drug product and as an analytical standard. This compound can be synthesized from erythromycin A, but it is not active against bacteria. Clarithromycin EP Impurity K has been shown to have metabolite properties in animals and humans, including metabolism studies with HPLC standards.

Memantine impurity IV is a hydrolysis product of memantine. It appears as a white to off-white powder and has a molecular weight of 198.1 g/mol. Memantine impurity IV is an intermediate in the production of memantine and is therefore not used for any other purpose. The compound contains hydroxy groups, hydroxy, alcohols, and bridgehead groups which are efficient at hydrolyzing to form amino acids.

Erythromycin impurity M is a natural, API impurity (impurity standard) that is a metabolite of erythromycin. It has been synthesized as a high purity HPLC standard to meet the requirements of pharmacopoeia and drug development. Erythromycin impurity M is an analytical reference material with CAS number 528-73-2.

Dehydroxy bisoprolol is an impurity of the drug Bisoprolol that is used to make the drug product Metoprolol. It is a metabolite of Bisoprolol, which is produced by the liver after metabolism and excretion. Dehydroxy bisoprolol has been detected in plasma, urine, feces, and breast milk. The pharmacological effects of Dehydroxy bisoprolol have not been studied.

2-Carboxybenzoyl amlodipine is a metabolite of the antihypertensive drug amlodipine. It is a white crystalline solid that is soluble in water. 2-Carboxybenzoyl amlodipine can be used as an impurity standard for HPLC analyses, and as an analytical standard for the determination of amlodipine in human plasma.

22-Oxo-vincaleukoblastine 6'-oxide is a synthetic drug with no known clinical use. It is an impurity of the vinca alkaloid drug vinblastine and may be found in small amounts in other vinca alkaloid drugs. 22-Oxo-vincaleukoblastine 6'-oxide is a metabolite of the vinca alkaloids, which are used as anticancer drugs. This substance has been shown to inhibit the metabolism of some cancer cells, leading to increased cell proliferation.
