Description

2-Thiophenecarboxylicacid,3-Amino-,Hydrazide(9Ci) is a specialized heterocyclic building block featuring both amino and hydrazide functional groups on a thiophene core. This unique molecular architecture makes it a valuable intermediate for synthesizing complex molecules in advanced research and development. It is primarily sought after by pharmaceutical and agrochemical R&D teams for creating novel active ingredients, such as potential enzyme inhibitors or ligands for metal complexes. Its precise structure offers chemists a versatile handle for constructing libraries of compounds with targeted biological or material properties.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting specific enzymes or receptors.
• Agrochemical Research: Used in the development of new pesticides, herbicides, or fungicides where the thiophene scaffold imparts specific bioactivity.
• Ligand Synthesis: Serves as a chelating agent or ligand precursor in coordination chemistry for creating catalysts or metal-organic frameworks (MOFs).
• Material Science: A building block for organic electronic materials, such as conductive polymers or semiconductors, due to the electron-rich thiophene ring.
• Chemical Biology Probes: Utilized in the design of molecular probes for studying biological processes and protein interactions.
• Custom Synthesis & Contract Manufacturing: A critical raw material for fine chemical manufacturers producing bespoke compounds for client R&D projects.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties. For long-term storage, consider using a desiccant in the storage environment.
