Description

4-Aminocinnamic Acid Hydrochloride is a key organic intermediate and building block in fine chemical synthesis. Its value lies in the dual functionality of the amino and carboxylic acid groups, which can be further modified to create a wide range of complex molecules. This compound is particularly sought after by researchers and manufacturers in the pharmaceutical and agrochemical industries for the development of new active ingredients and specialty chemicals.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of various active pharmaceutical ingredients (APIs), particularly those with cinnamic acid or aniline-derived backbones.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and plant growth regulators.
• Peptide Mimetics & Conjugation: The carboxylic acid group enables its use in creating peptide analogs or for conjugation chemistry in drug design and bioconjugation applications.
• Organic Light-Emitting Diodes (OLEDs): Acts as a starting material for synthesizing advanced organic semiconductors and charge-transport materials.
• Dye & Pigment Manufacturing: Utilized as a building block for producing specialized azo dyes and organic pigments.
• Academic & Industrial Research: A valuable reagent in medicinal chemistry and material science research for constructing complex molecular libraries.

Quality Control

Our 4-Aminocinnamic Acid Hydrochloride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation via IR and NMR, and residual solvent analysis. We provide a Certificate of Analysis (COA) with every shipment, detailing all specifications and test results to ensure traceability and compliance with your research or production requirements.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
