Description

1,3-Cyclohexanedicarbonyl Dichloride, trans- (8Ci,9Ci) is a high-purity, reactive diacid chloride derivative of trans-1,3-cyclohexanedicarboxylic acid. This compound matters as a critical bifunctional building block for introducing the rigid, alicyclic trans-1,3-cyclohexane moiety into advanced molecular architectures. It is primarily needed by R&D chemists and process development teams in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing novel active ingredients, ligands, and high-performance materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those requiring a rigid, alicyclic backbone to influence pharmacokinetics and receptor binding.
• Agrochemical Synthesis: Used in creating advanced herbicides, fungicides, and plant growth regulators with enhanced stability and efficacy.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for producing specialty polyamides, polyesters, and epoxy resins with improved thermal and mechanical properties.
• Ligand & Catalyst Development: Employed in the preparation of chiral ligands and metal-organic frameworks (MOFs) for asymmetric catalysis and separation technologies.
• Organic Synthesis Reagent: A versatile reagent for introducing the trans-cyclohexane-1,3-dicarbonyl unit into complex molecules via amidation, esterification, or polymerization reactions.
• Cosmetic & Personal Care Ingredients: Intermediate for synthesizing specialty esters and polymers used in advanced cosmetic formulations.

Quality Control

Our 1,3-Cyclohexanedicarbonyl Dichloride, trans- is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for advanced synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from strong bases, alcohols, and water.
