Olanzapine EP Impurity G - Introduction

2-methyl-4-(1-piperazinyl)-10H-thienol[2,3-b][1,5]benzodiazepine is an organic compound also known as TPZ(Thiophen film 10h-phenol).

Nature:
-Appearance: White to light yellow crystal
-Molecular formula: C16H11N3S
-Molecular weight: 277.34g/mol
-Melting point: 220-225 degrees Celsius
-Solubility: Soluble in organic solvents, slightly soluble in water

Use:
-Pharmaceutical field: as a kind of anti-tumor drugs. TPZ can be reduced to active metabolites in vivo, causing DNA damage and inducing cell apoptosis, so as to achieve the effect of tumor treatment.
-Other applications: TPZ is also used as an organic dye, photoelectric material and photosensitizer.

Method:
TPZ is usually synthesized as follows:
1.2-methyl -4-bromothiophene and 1-piperazine methylamine reaction, through the reduction and nucleophilic substitution reaction to form the target compound.

Safety Information:
The toxicity and safety of TPZ have not been fully studied. When used in the laboratory, general laboratory safety practices should be followed, such as wearing appropriate personal protective equipment (such as laboratory gloves, protective glasses) and ensuring that the operation is carried out under well-ventilated conditions. In addition, more detailed security assessments and protective measures should be carried out on a case-by-case basis.
