Description

Benzonitrile, 3,4-Diformyl- (8Ci,9Ci) CAS NO 19047-20-2 is a high-purity, multi-functional aromatic nitrile derivative featuring two formyl groups on the benzene ring. This compound serves as a versatile and critical advanced organic intermediate for synthesizing complex heterocyclic systems and functional materials. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and specialty chemical industries for constructing novel molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of kinase inhibitors and other heterocyclic drug candidates.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators requiring specific aromatic substitution patterns.
• Ligand and Chelator Precursor: The formyl and nitrile groups allow for the construction of polydentate ligands used in catalysis and metal complexation.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers, coordination polymers (MOFs), and organic electronic materials.
• Fine Chemical Synthesis: Employed in multi-step organic synthesis for creating complex dyes, pigments, and photoactive compounds.

Quality Control

Every batch of our Benzonitrile, 3,4-Diformyl- is produced and tested under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles to ensure it meets the exacting standards for advanced synthetic applications. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated research and development.

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 and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize moisture uptake.
