Description

Cyclopentanecarbaldehyde 2,4-Dinitrophenylhydrazone is a high-purity analytical reference standard and chemical derivative, primarily used for the identification and quantification of carbonyl compounds. Its value lies in its role as a key reagent for forming stable, colored hydrazone derivatives, which are essential for spectroscopic and chromatographic analysis. This product is critical for research and quality control laboratories in the pharmaceutical, agrochemical, and fine chemical industries, where precise analytical methods are paramount.

Application

• Analytical Chemistry Standard: Serves as a certified reference material (CRM) for calibrating instruments and validating analytical methods for carbonyl group detection.
• Carbonyl Compound Derivatization: Used to derivative aldehydes and ketones into stable 2,4-dinitrophenylhydrazones (DNPHs) for enhanced detection in HPLC and UV-Vis spectroscopy.
• Pharmaceutical Impurity Profiling: Employed in the identification and quantification of aldehyde-based impurities or degradation products in active pharmaceutical ingredients (APIs).
• Environmental Analysis: Applied in methods for detecting trace levels of airborne carbonyl compounds, such as formaldehyde and acetaldehyde, in environmental monitoring.
• Organic Synthesis Intermediate: Acts as a protected form of cyclopentanecarbaldehyde or as a building block in the synthesis of more complex heterocyclic compounds.
• Food and Flavor Chemistry: Utilized in the analysis of flavor compounds and potential contaminants that contain aldehyde functional groups.
• Academic and Industrial Research: A fundamental reagent for mechanistic studies and method development in organic and analytical chemistry research projects.

Quality Control

Our Cyclopentanecarbaldehyde 2,4-Dinitrophenylhydrazone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for analytical and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and identification results is provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
