Description

1-Cyclopentene-1-Carboxylicacid,2-(2-Formylhydrazino)-,Ethylester(9Ci) CAS NO 163353-19-3 is a specialized organic compound featuring a cyclopentene core functionalized with a carboxylic acid ethyl ester and a formylhydrazino group. This unique molecular architecture makes it a valuable advanced intermediate for synthesizing complex heterocyclic compounds and active pharmaceutical ingredients (APIs). It is primarily sought by research institutions and pharmaceutical R&D departments engaged in medicinal chemistry and process development.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) or anti-inflammatory pathways.
• Agrochemical Research: Used in the development of new herbicides, fungicides, or plant growth regulators due to its reactive hydrazine moiety.
• Chemical Synthesis: Serves as a versatile precursor for creating complex nitrogen-containing heterocycles like pyrazoles and triazoles.
• Material Science: Potential monomer or cross-linking agent in the development of specialty polymers with unique thermal or mechanical properties.
• Academic & Contract Research: Essential reagent for methodological studies in organic synthesis and catalysis research.

Quality Control

Our 1-Cyclopentene-1-Carboxylicacid,2-(2-Formylhydrazino)-,Ethylester(9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure high purity and structural identity. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment to support your quality assurance and regulatory needs.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
