For B2B procurement managers and R&D scientists in the chemical and pharmaceutical industries, identifying reliable sources for critical intermediates like 3,4-Dichlorobenzaldehyde (CAS 6287-38-3) is paramount. This compound, a white crystalline solid with a distinct chemical structure, serves as a vital building block in numerous organic synthesis pathways. Understanding its properties, applications, and the nuances of sourcing from manufacturers is key to ensuring consistent quality and cost-effectiveness.

What is 3,4-Dichlorobenzaldehyde?

3,4-Dichlorobenzaldehyde, identified by CAS number 6287-38-3, is an aromatic aldehyde characterized by two chlorine atoms substituted at the 3 and 4 positions of the benzene ring. Its molecular formula is C7H4Cl2O, and it typically presents as white crystals with a melting point around 44°C and a boiling point of approximately 247-248°C. It exhibits limited solubility in water but is soluble in hot alcohol and ether, making handling and reaction setup straightforward for many applications.

Key Applications in Industry

The primary utility of 3,4-Dichlorobenzaldehyde lies in its role as an intermediate in organic synthesis. Its most well-documented application is in the synthesis of pharmaceuticals, notably as a precursor for drugs like nitroquine. Beyond pharmaceuticals, its reactive aldehyde group and the presence of chlorine atoms make it a versatile starting material for creating a wide array of fine chemicals, potentially including advanced agrochemicals, dyes, and specialized materials. For R&D scientists, its predictable reactivity opens doors to exploring novel molecular structures.

Sourcing Strategies and Considerations

When looking to buy 3,4-Dichlorobenzaldehyde, particularly from China, several factors should be considered. Firstly, purity is critical. Most suppliers will offer a purity of 98.0% or higher, with 99% being a common standard for industrial applications. Always request a Certificate of Analysis (COA) to verify the specifications, including appearance, assay, and melting point. Minimum order quantities can vary, with 1kg or 25kg drums being typical packaging options.

Secondly, the reputation and reliability of the manufacturer or supplier are crucial. Engaging with established companies that have a strong track record in chemical manufacturing ensures not only product quality but also consistent supply and adherence to international standards. When you inquire about the price for 3,4-Dichlorobenzaldehyde, compare offers from multiple reputable sources, but do not compromise on quality for a slightly lower cost.

Thirdly, logistical support, including safe packaging and delivery options, is important. Manufacturers often provide details on storage conditions, typically cool and dry places, to maintain product integrity.

Finding a Trusted Manufacturer

For procurement managers, partnering with a manufacturer that offers excellent customer service, competitive pricing, and a commitment to quality is essential. Look for suppliers who can provide detailed technical data sheets (TDS) and safety data sheets (SDS). When you make a purchase inquiry for 3,4-Dichlorobenzaldehyde, clearly state your purity requirements and expected order volume.

In conclusion, 3,4-Dichlorobenzaldehyde (CAS 6287-38-3) is a valuable intermediate for chemical synthesis. By understanding its applications and adopting a strategic approach to sourcing from reliable manufacturers, businesses can secure a consistent supply of this essential chemical, driving innovation and product development forward.
