Description

5-(4-Chlorophenyl)-4-Hydrazinothieno[2,3-D]Pyrimidine is a high-purity, heterocyclic organic compound featuring a thienopyrimidine core functionalized with a chlorophenyl group and a reactive hydrazine moiety. This specific molecular architecture makes it a critical building block (advanced intermediate) for the synthesis of novel, complex molecules in pharmaceutical research and development. It is primarily sought after by research chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating targeted libraries and active ingredients.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of potential drug candidates, particularly for kinase inhibitors and other targeted therapies.
• Agrochemical Research: Used in the development of new herbicides, fungicides, or insecticides, leveraging its heterocyclic structure for bioactivity.
• Chemical Biology Probe Development: Employed in creating molecular tools to study enzyme function and biological pathways due to its modifiable hydrazine group.
• Material Science Research: Investigated as a monomer or functional additive for creating specialized polymers with unique electronic or thermal properties.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for client-specific synthesis projects requiring this precise intermediate.

Quality Control

Every batch of 5-(4-Chlorophenyl)-4-Hydrazinothieno[2,3-D]Pyrimidine is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure identity, purity, and consistency for your research and development needs. A Certificate of Analysis (COA) detailing purity (typically by HPLC), identity confirmation (IR, NMR), and impurity profiles is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, prolonged exposure to air should be minimized. Keep the container tightly sealed when not in use.
