Description

2-Thiophenepropiolaldehyde, 5-Methyl- (7Ci) is a specialized heterocyclic building block featuring both a thiophene ring and a propiolaldehyde functional group. This unique molecular architecture makes it a valuable synthon for the development of novel materials and active pharmaceutical ingredients (APIs). It is primarily sought by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular frameworks.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders or possessing anti-inflammatory properties.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides, leveraging the bioactivity of the thiophene moiety.
• Material Science: Acts as a monomer or cross-linking agent in the production of conductive polymers, organic semiconductors, and non-linear optical (NLO) materials.
• Ligand Synthesis: Employed for creating novel chelating ligands in catalysis and metal-organic frameworks (MOFs).
• Chemical Biology: Utilized as a probe or labeling reagent due to its reactive aldehyde group, which can form stable conjugates.
• Academic & Industrial R&D: A fundamental building block for methodological development in organic synthesis and heterocyclic chemistry.

Quality Control

Our 2-Thiophenepropiolaldehyde, 5-Methyl- (7Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical characterization to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing results from NMR, HPLC, and GC-MS are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Allow the container to reach room temperature before opening to minimize moisture ingress.
