Description

Benzoyl Chloride, 3-Formyl- (9Ci) CAS NO 75650-38-3 is a highly reactive aromatic acid chloride derivative, serving as a critical multifunctional building block in advanced organic synthesis. Its dual functionality, combining the electrophilic benzoyl chloride group with a formyl substituent, enables precise molecular construction for high-value intermediates. This compound is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce both benzoyl and aldehyde moieties in a single step.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring benzamide or benzaldehyde-derived structures.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators where its reactive sites allow for the creation of complex heterocyclic systems.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing specialized chelating ligands and organocatalysts used in asymmetric synthesis.
• Polymer Chemistry: Employed in the production of specialty polymers and resins, where it can act as a monomer or cross-linking agent to impart specific thermal or mechanical properties.
• Dyestuff and Pigment Manufacturing: Integral to the synthesis of complex organic dyes and high-performance pigments, contributing to color fastness and stability.
• Fine Chemical Production: A versatile reagent for constructing complex aromatic aldehydes and ketones used in flavors, fragrances, and electronic chemicals.

Quality Control

Our Benzoyl Chloride, 3-Formyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as bases, alcohols, and amines.
