Description

3-Chloro-4-Hydroxycinnamic Acid is a functionalized cinnamic acid derivative characterized by its chloro and phenolic hydroxyl substituents, which impart significant reactivity and utility in advanced organic synthesis. This compound serves as a versatile and high-value pharmaceutical intermediate and building block for the development of complex molecules. It is primarily sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of drug candidates, particularly those targeting inflammation, metabolic disorders, and central nervous system (CNS) diseases.
• Agrochemical Synthesis: Used as a building block for developing new herbicides, fungicides, and plant growth regulators with enhanced efficacy.
• Organic Light-Emitting Diodes (OLEDs): Serves as a starting material for synthesizing advanced organic semiconductors and electron-transport materials.
• UV Absorber & Polymer Stabilizer: Incorporated into polymer formulations to improve light stability and durability due to its phenolic and conjugated structure.
• Biochemical Research: Utilized as a substrate or inhibitor in enzymatic studies and as a probe in biochemical assays.
• Fine Chemical Synthesis: Acts as a versatile synthon for producing flavors, fragrances, and other high-value specialty chemicals through further functionalization.

Quality Control

Our 3-Chloro-4-Hydroxycinnamic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical and research applications. Certificates of Analysis (COA) documenting all critical parameters 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, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
