Description

trans-1,4-Cyclohexane Dicarbohydrazide is a high-purity, symmetrical dihydrazide derivative of cyclohexane dicarboxylic acid. This specialized chemical serves as a critical building block and cross-linking agent in advanced polymer synthesis and specialty material formulations. It is essential for manufacturers in the polymer, pharmaceutical, and fine chemical industries seeking to develop materials with enhanced thermal stability, mechanical properties, or specific functional groups.

Application

• Polymer Cross-Linking Agent: A key intermediate for synthesizing high-performance polyurethanes, polyamides, and other thermosetting resins, imparting improved thermal and chemical resistance.
• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and drug conjugates, particularly where a rigid, symmetrical linker is required.
• Epoxy Curing Agent: Functions as a hardener for epoxy resin systems, contributing to high cross-link density and enhanced mechanical properties in composite materials.
• Metal Chelation & Catalyst Ligand: The dual hydrazide groups can act as ligands for metal ions, useful in catalysis and metal-organic framework (MOF) synthesis.
• Flame Retardant Synergist: Incorporated into polymer formulations to enhance flame retardancy through nitrogen-containing synergism.
• Adhesive & Coating Formulations: Improves adhesion and durability in high-performance industrial coatings and adhesives.

Quality Control

Our trans-1,4-Cyclohexane Dicarbohydrazide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, IR, and titration methods, to ensure it meets precise specifications for purity, identity, and impurity profiles. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture.
