Description

Phthalamic Acid CAS NO 88-97-1 is a versatile organic intermediate derived from phthalic anhydride. This compound is valued for its bifunctional nature, featuring both a carboxylic acid and an amide group, which makes it a key building block in synthetic organic chemistry. It is primarily sought after by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for the synthesis of active ingredients, dyes, and functional materials.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of various active pharmaceutical ingredients (APIs), particularly those with complex amide or imide structures.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators, contributing to crop protection solutions.
• Polymer & Resin Modifier: Serves as a monomer or cross-linking agent to introduce specific functional groups into polymers, enhancing properties like adhesion or thermal stability.
• Dye & Pigment Manufacturing: Acts as an intermediate in the synthesis of phthalocyanine dyes and other complex colorants.
• Chemical Research & Development: Employed in academic and industrial R&D labs as a versatile scaffold for novel compound libraries and material science.
• Corrosion Inhibitor Formulation: Used in specialty chemical formulations designed to protect metal surfaces in industrial processes.

Quality Control

Our Phthalamic Acid is produced 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 industrial and research applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
