Description

Salicylaldehyde CAS NO 90-02-8 is an aromatic aldehyde characterized by a phenolic hydroxyl group ortho to the formyl group, giving it unique chemical reactivity. This versatile intermediate is crucial for synthesizing a wide range of high-value compounds, including pharmaceuticals, agrochemicals, and complexing agents. It is an essential raw material for manufacturers in the fragrance, fine chemical, and pharmaceutical industries seeking to produce coumarin derivatives, salicylaldimine ligands, and other specialty chemicals.

Application

• Pharmaceutical Intermediates: Key precursor in the synthesis of coumarin, a core structure for anticoagulants and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of certain herbicides, fungicides, and plant growth regulators.
• Fragrance and Flavor Industry: Serves as a building block for synthetic heliotropin (piperonal) and other aroma chemicals.
• Metal Chelation and Catalysis: Forms salicylaldimine (Schiff base) ligands, which are vital in coordination chemistry for catalysis and metal ion extraction.
• Dye and Pigment Manufacturing: Intermediate in the production of certain azo dyes and optical brighteners.
• Photographic Chemicals: Used in the synthesis of specific compounds for photographic developers.
• Organic Synthesis: A versatile reagent for synthesizing heterocyclic compounds, including benzofurans and chromones.

Quality Control

Our Salicylaldehyde is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including GC/HPLC for purity and identity confirmation, to ensure it meets exacting specifications for industrial and fine chemical applications. Certificates of Analysis (COA) documenting all critical parameters 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, well-ventilated area away from incompatible materials such as strong acids, bases, and oxidizing agents. Due to its properties of being easily oxidized (store under inert atmosphere) and compatibility with strong acid/organic solvent, it is recommended to keep containers tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal purity and shelf life.
