Description

2-Chloro-3,4-Dimethoxycinnamic Acid is a high-purity synthetic intermediate characterized by its cinnamic acid backbone with chloro and dimethoxy substituents. This compound is valued for its role as a versatile building block in the synthesis of more complex organic molecules, particularly in fine chemical and pharmaceutical research. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced material sectors for constructing target compounds with specific electronic and steric properties.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), especially those targeting neurological or inflammatory pathways.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators.
• Organic Light-Emitting Diodes (OLEDs): Serves as a starting material for synthesizing electron-transport or host materials in OLED displays and lighting.
• Liquid Crystal & Advanced Material Research: Employed in creating mesogenic units for liquid crystals or monomers for specialized polymers.
• Chemical Biology & Proteomics: Can be utilized as a scaffold or linker in the development of molecular probes and enzyme inhibitors.
• Academic & Contract Research: Essential for methodological studies and synthetic route exploration in university and CRO laboratories.

Quality Control

Our 2-Chloro-3,4-Dimethoxycinnamic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

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.
