General Information

Brexpiprazole Impurities and Brexpiprazole 

Daicel Pharma synthesizes Brexpiprazole impurities of exceptional quality, such as 5-hydroxyquinolin-2(1H)-one, Brexpiprazole 3,4-dihydro Impurity, Brexpiprazole 5-1H-Quinolin-2-one, etc. These impurities are crucial to assess the purity, reliability, and safety of Brexpiprazole, an active pharmaceutical ingredient. Besides, Daicel Pharma provides a custom synthesis of Brexpiprazole impurities to meet clients’ demands for delivery worldwide.

Brexpiprazole [CAS: 913611-97-9] is an antipsychotic medication for treating schizophrenia and major depressive disorders. It is similar in structure to Aripiprazole.

Brexpiprazole: Use and Commercial Availability  

Brexpiprazole is available under the brand name Rexulti® for treating schizophrenia. It treats major depressive disorder (MDD) and is atypical antipsychotic.

Brexpiprazole Structure and Mechanism of Action Brexpiprazole Structure and Mechanism of Action

The chemical name of Brexpiprazole is 7-[4-(4-Benzo[b]thien-4-yl-1-piperazinyl)butoxy]-2(1H)-quinolinone. Its chemical formula is C25H27N3O2S, and its molecular weight is approximately 433.6 g/mol.

The mechanism of action of Brexpiprazole is unknown for treating schizophrenia.

Brexpiprazole Impurities and Synthesis

Brexpiprazole impurities are organic and inorganic impurities. Organic impurities include starting materials, reagents, intermediates, degradation products, and mutagenic and genotoxic impurities. Inorganic impurities include heavy metals and residual solvents. They can form during the synthesis1, storage, or transportation of Brexpiprazole. It is essential to control and monitor the levels of impurities through various methods, such as quality control testing, stability studies, and proper storage and handling of the drug substance and finished product to ensure the safety and efficacy of Brexpiprazole.

Daicel Pharma offers a Certificate of Analysis (CoA) for Brexpiprazole impurity standards, such as 5-hydroxyquinolin-2(1H)-one, Brexpiprazole 3,4-dihydro Impurity, Brexpiprazole 5-1H-Quinolin-2-one, etc., generated from an analytical facility compliant with cGMP standards. The CoA includes a comprehensive characterization report comprising data from techniques like 1H NMR, 13C NMR, IR, MASS, and HPLC purity. Furthermore, on request, we can provide additional data like 13C-DEPT and CHN. Daicel Pharma can prepare unknown Brexpiprazole impurities or degradation products and labeled compounds to assess the effectiveness of generic Brexpiprazole. We also offer Brexpiprazole-D8, a deuterium-labeled Brexpiprazole standard useful in bio-analytical research, such as BA/BE studies. A complete characterization report accompanies every delivery.
