For any chemical intermediate to be truly effective, particularly in demanding fields like pharmaceuticals and fine chemicals, understanding its purity and specifications is paramount. 2-Nitrobenzaldehyde (CAS 552-89-6) is no exception. This light yellow crystalline powder is valued for its reactive functional groups, but its performance in complex synthetic pathways heavily relies on its quality. Manufacturers and end-users alike place significant emphasis on the assay, appearance, and other physical-chemical parameters that define its grade.

A key specification for 2-Nitrobenzaldehyde is its assay, which typically refers to the percentage of the target compound present. High-quality 2-Nitrobenzaldehyde commonly features an assay of ≥99.0%, with actual results often reaching 99.49% or higher, as reported by reputable suppliers. This high purity level is crucial for ensuring predictable reaction outcomes and minimizing the formation of unwanted byproducts, which is especially critical in pharmaceutical manufacturing where strict regulatory standards apply. When procuring 2-Nitrobenzaldehyde, confirming its assay is a primary step.

The appearance is another vital indicator. Described as a light yellow to pale yellow crystalline powder, any deviation from this description could signal contamination or degradation. Specifications also include moisture content, which should be kept to a minimum (e.g., ≤0.50%), as excess water can interfere with certain reactions or affect storage stability. The melting point range, typically between 41-46 °C, is also a critical parameter used to verify purity. A broader or lower melting point can indicate the presence of impurities.

Companies like NINGBO INNO PHARMCHEM CO.,LTD. understand the importance of these specifications. As a leading 2-Nitrobenzaldehyde supplier, they provide detailed Certificates of Analysis (CoA) that document these critical parameters. This transparency allows researchers and manufacturers to confidently purchase 2-Nitrobenzaldehyde, assured that the material meets the required standards for their specific applications, whether it's for synthesizing complex pharmaceutical intermediates or developing new colorants. Reliable specifications are the bedrock of successful chemical synthesis.
