Thiothixene [CAS: 5591-45-7] belongs to a class of medications known as conventional antipsychotics. It alleviates the symptoms of schizophrenia.
Thiothixene: Use and Commercial Availability
Thiothixene is an antipsychotic for treating schizophrenia, a psychiatric disorder characterized by disrupted or atypical thinking, diminished interest in life, and intense or inappropriate emotions. It treats psychotic disorders and shares a distinct chemical and pharmacological resemblance with piperazine derivatives of the phenothiazine series. Thiothixene is available under Navane, which contains the active ingredient, Thiothixene.
Thiothixene Structure and Mechanism of Action
The chemical name of Thiothixene is N, N-Dimethyl-9-[3-(4-methyl-1-piperazinyl)propylidene]-9H-thioxanthene-2-sulfonamide. Its chemical formula is C23H29N3O2S2, and its molecular weight is approximately 443.6 g/mol.
Thiothixene blocks postsynaptic receptors with anxiolytic, anti-depressive, and anti-aggressive properties.
Thiothixene Impurities and Synthesis
During the preparation1 of Thiothixene, impurities can form due to the utilization of starting materials, intermediates, or reagents. These impurities diminish the drug’s effectiveness and pose risks to patients. Therefore, it is crucial to control their levels closely.
Daicel Pharma supplies a Certificate of Analysis (CoA) for Thiothixene impurity standards, which includes N-desmethyl thiothixene (Mixture of E/Z isomers), Thiothixene impurity 1, Thiothixene impurity (DHTS impurity),(E)-Thiothixene and more. The CoA is from an analytical facility adhering to current Good Manufacturing Practices (cGMP). It includes comprehensive characterization data such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity2. Additionally, upon request, we can provide additional characterization data such as 13C-DEPT. Daicel Pharma also can generate unknown impurities or degradation products of Thiothixene. A complete characterization report accompanies each delivery.
