4-Chlorobenzaldehyde CAS 104-88-1

What 4-Chlorobenzaldehyde Is

4-chlorobenzaldehyde is a substituted benzaldehyde carrying a chlorine atom at the para position, sold as white to pale yellow crystals or flakes with a characteristic aromatic odor. The aldehyde group gives the molecule its main reactivity: oxidation yields 4-chlorobenzoic acid, reduction yields 4-chlorobenzyl alcohol, and condensation or imine formation opens routes to many larger molecules. It is slightly soluble in water and freely soluble in common organic solvents. With a melting point just below 50 °C, the solid can soften or melt in hot weather, so cool, shaded handling keeps it crystalline. UATChem supplies industrial and pharma oriented material, with assay and moisture reported on the COA for each lot.

Pharma, Agrochemical and Other Synthesis

• Pharmaceutical intermediates. An aromatic aldehyde block in API and fine drug synthesis for condensation, imine and heterocycle building steps, including antihistamine routes.
• Agrochemicals. An intermediate for triazole fungicides and plant growth regulators and other pesticide syntheses.
• Dyes and optical brighteners. A feed intermediate for dyes, organic pigments and fluorescent whitening agents.
• Fragrance and derivatives. Used in fragrance and flavor synthesis and polymer additives, and as a precursor for halogen exchange derivatives such as 4-fluorobenzaldehyde.

Typical Specifications

Industrial and pharma oriented grades differ in assay and moisture; values are reported on the COA for each lot, and the physical constants below identify the material.

Packaging, Documents and Ordering

• Packed in 25 kg fiber drums and 200 kg drums; the low melting solid is kept sealed, cool, shaded and temperature controlled in warm weather to avoid softening or melting.
• 4-chlorobenzaldehyde irritates the skin, eyes and respiratory tract and may sensitize, so gloves, goggles and ventilation are used, with transport classification shown on the SDS. Every lot carries a COA with assay, moisture and melting point, together with TDS and SDS, and samples are supported.
• For a quote, UATChem needs the grade (industrial or pharma oriented), quantity, packing and destination port.

FAQ

Q: What is 4-chlorobenzaldehyde used for?

A: It is an aromatic aldehyde for pharma and agrochemical intermediates, dyes, optical brighteners and fragrance synthesis.

Q: Is 4-chlorobenzaldehyde a solid or a liquid?

A: It is a low melting solid (46 to 49 °C) that can soften in hot weather, so it is stored and shipped cool and shaded.

Q: How is 4-chlorobenzaldehyde packed?

A: UATChem supplies it in 25 kg fiber drums and 200 kg drums, sealed, cool and shaded, with COA and SDS for each export lot.
