<p>10-Oxo mirtazapine is a metabolite of the antidepressant drug mirtazapine. It is an impurity in the HPLC standard for mirtazapine and has been shown to be pharmacologically active in animal models. 10-Oxo mirtazapine has also been found to be an impurity in other drugs, such as fluoxetine hydrochloride, but it is not known if it has any activity.</p>

<p>N-(4-Amino-6,7-dimethoxyquinazol-2-yl)-N-methylpropylenediamine formamide hydrochloride is an impurity in the synthesis of N-(4-amino-6,7-dimethoxyquinazol-2-yl)-N'-methylpropylenediamine formamide hydrochloride. It is a white solid that can be used as an analytical reference standard for HPLC. It has been detected in the urine of people taking this drug and can be used to identify the presence of this drug in urine samples.</p>

<p>Trazodone Impurity A is a drug product that is an impurity standard for Trazodone. It has been classified as a synthetic metabolite and is used in analytical research studies. Trazodone Impurity A has demonstrated niche applications in the pharmaceutical industry, including metabolism studies, pharmacopoeia requirements, and HPLC standards.</p>

<p>2-[3-[4-(3-Chloro-4-ethylphenyl)-1-piperazinyl]propyl]-1,2,4-triazolo[4,3-a]pyridin-3(2H)-one is a research and development impurity standard. Impurities are the substances that are not intentionally added to the drug product but can be generated from the synthesis process or from the raw materials. This substance has been used as a synthetic intermediate in the production of other drugs and as an analytical reference for HPLC analysis. It is used to help develop new drugs by providing data about metabolites and possible toxic effects on humans.</p>

<p>N2-Methyl alfuzosin is an impurity of Alfuzosin, a drug used to treat benign prostatic hyperplasia. It can be used as an HPLC standard for the detection and quantification of Alfuzosin in pharmaceutical products. N2-Methyl alfuzosin is a metabolite of Alfuzosin that is formed by cytochrome P450 3A4. It has been shown to have anti-inflammatory effects, which may be due to its inhibition of prostaglandin synthesis.</p>

<p>Furegrelate is an analytical reference standard for the hydroxylation of 4-(4-amino-6,7-dimethoxy-2-quinazolinyl)-1-piperazinyl[(5S)-tetrahydro-5-methyl-2-furanyl]-methanone. Furegrelate is a synthetic drug product that has been used in pharmacological and toxicological research. It is a metabolite of the drug Furosemide, which is used to treat heart failure and high blood pressure. Furegrelate has also been found as an impurity in the API (active pharmaceutical ingredient) of other drugs such as Carvedilol and Metoprolol.</p>

<p>(S)-Carvedilol is a non-selective β/α-1 blocker.It exerts protection against the vascular or cardiac toxicity of Doxorubicin (DOX).</p>

<p>(S)-Terazosin is an active S-enantiomer of Terazosin.</p>

<p>(R)-Carvedilol is a non-selective blocker of β/α-1. (R)-Carvedilol exerts protection against the vascular or cardiac toxicity of Doxorubicin (DOX).</p>

<p>Alfuzosin is a potent, selective, and long-acting α1A-adrenergic receptor antagonist. It is used to treat benign prostatic hyperplasia (BPH) in males. Alfuzosin is also used as an antihypertensive agent, for the treatment of pheochromocytoma, and for the treatment of benign prostatic hyperplasia in males. The hydrogenation of 2,3,4,5-tetradehydroalfuzosin to alfuzosin hydrochloride is performed by liquid hydrogenation or by hydrogenation on a palladium catalyst in a mixture of dimethylformamide and hexamethylphosphoramide. This process minimizes the formation of impurities such as 2,3,4-trimethoxy alfuzosin.</p>

<p>1-Oxo mirtazapine is a metabolite of mirtazapine. It is a synthetic compound and is not found in nature. This product is a research and development impurity standard for the preparation of drug product, which has been synthesized to be highly pure. The material is used for drug development, including pharmacopoeia requirements for analytical studies and metabolism studies. 1-Oxo mirtazapine has been shown to have niche applications in pharmacopoeia and as an HPLC standard.</p>
