2-chlorobenzaldehyde

2-Chlorobenzaldehyde (CAS 89-98-5), also known as o-chlorobenzaldehyde, is an aromatic aldehyde used as a reactive intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty dyes.

Its chloro-substituted structure makes it a valued building block where precise reactivity at the aldehyde and ring positions drives downstream synthesis efficiency in various chemical processes.

In pharmaceutical manufacturing, it serves as a key precursor in the synthesis of active ingredients, including antihistamines and antimicrobial compounds for the healthcare sector.

Dye and pigment producers use it to construct azo and triarylmethane colorants applied in textile and paper dyeing processes, ensuring high-quality results for industrial applications.

In printing and packaging, it contributes to the formulation of specialty inks where reactive intermediates determine color fastness and substrate adhesion for commercial use.

It also functions as a biocide intermediate, incorporated into preservation systems for leather treatment and industrial process fluids to maintain product integrity and safety.

The product is supplied as a clear to pale yellow liquid in standard commercial packaging, including drums and IBC containers for bulk orders and large-scale distribution.

Technical grade is the primary specification, with purity levels typically at 98% or higher as confirmed by GC analysis to meet rigorous industrial manufacturing requirements.
