Description

2-Thiophenecarboxaldehyde, 5-(2-Hydroxyethyl)- (9Ci) is a specialized heterocyclic aldehyde building block that combines a reactive formyl group with a terminal hydroxyethyl side chain on a thiophene ring. This unique bifunctional structure makes it a valuable intermediate for synthesizing complex molecules in advanced research and development. It is particularly sought after by pharmaceutical, agrochemical, and material science industries for applications in drug discovery, ligand synthesis, and the creation of functional polymers.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for compounds targeting the central nervous system or possessing anti-inflammatory properties.
• Agrochemical Synthesis: Used in the development of new generation pesticides and herbicides, where the thiophene moiety can contribute to biological activity.
• Ligand and Catalyst Development: Serves as a versatile starting material for creating chelating ligands used in catalysis and metal-organic frameworks (MOFs).
• Functional Polymer & Material Science: Incorporated into polymer backbones to impart specific electronic or optical properties, useful in organic electronics and sensor technologies.
• Chemical Research & Development: Employed in academic and industrial R&D for exploring new synthetic pathways and creating libraries of novel heterocyclic compounds.
• Fine Chemical Production: Acts as a building block for synthesizing dyes, pigments, and other performance chemicals.

Quality Control

Our 2-Thiophenecarboxaldehyde, 5-(2-Hydroxyethyl)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
