Description

1,3-Cyclohexanedicarbonyl Dichloride (9Ci) is a high-purity, reactive diacid chloride derivative of cyclohexane-1,3-dicarboxylic acid. This compound serves as a critical acylating agent and versatile building block in advanced organic synthesis, enabling the formation of amides, esters, and polymers. It is essential for R&D and production chemists in the pharmaceutical, agrochemical, and specialty polymer industries who require a reliable, high-quality intermediate for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those containing cyclohexane-based scaffolds.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators requiring specific dicarboxamide or diester functionalities.
• Polymer Chemistry: Monomer for the production of specialty polyamides, polyesters, and other condensation polymers with tailored thermal and mechanical properties.
• Organic Synthesis Reagent: Employed as a reactive acyl chloride in Friedel-Crafts acylation, esterification, and amidation reactions under Schotten-Baumann conditions.
• Ligand and Catalyst Preparation: Precursor for synthesizing chelating ligands used in coordination chemistry and catalysis.
• Material Science Research: Intermediate in the development of novel organic frameworks, dendrimers, and cross-linked materials.

Quality Control

Our 1,3-Cyclohexanedicarbonyl Dichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for synthetic intermediates. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture absorption.
