Description

2-Chloro-4-Formylbenzoic Acid is a versatile aromatic aldehyde and carboxylic acid derivative, serving as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both a reactive formyl group and a carboxylic acid moiety, makes it an indispensable intermediate for constructing complex molecular architectures. This compound is primarily sought after by research institutions and manufacturers in the pharmaceutical and agrochemical sectors for developing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules with benzaldehyde or benzoic acid backbones.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and plant growth regulators where the chloro and formyl groups enable specific bioactivity.
• Ligand and Catalyst Development: Serves as a starting material for creating chelating ligands in coordination chemistry and catalysis.
• Material Science Precursor: Employed in the synthesis of organic semiconductors, liquid crystals, and advanced polymers.
• Dyestuff and Pigment Intermediate: Utilized in the production of specialized dyes and colorants.
• Custom Synthesis and R&D: A valuable reagent for medicinal chemistry and process research in contract research organizations (CROs) and fine chemical companies.

Quality Control

Every batch of 2-Chloro-4-Formylbenzoic Acid is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment and is available upon request.

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 sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage of bulk quantities and to minimize exposure to air.
