For professionals in the microelectronics industry, particularly those involved in the formulation and manufacturing of photoresists, sourcing high-quality chemical intermediates is paramount. One such critical compound is 3,5-Dichlorobenzaldehyde (CAS 10203-08-4). Understanding its properties and where to procure it reliably can significantly impact production efficiency and final product performance. This guide aims to assist purchasing managers and R&D scientists in identifying dependable sources for this essential chemical.

Understanding 3,5-Dichlorobenzaldehyde

3,5-Dichlorobenzaldehyde is an organic compound characterized by a benzene ring substituted with two chlorine atoms and an aldehyde group. Its precise molecular structure and high purity make it an ideal building block for complex chemical syntheses. Its CAS number, 10203-08-4, is widely recognized in the chemical industry, signifying its importance as a commercial chemical intermediate. The compound typically appears as a white to slightly yellow fluffy powder, with a defined melting point range.

Key Applications in Photoresist Technology

The primary driver for the demand of 3,5-Dichlorobenzaldehyde in the B2B sector is its application in photoresist chemicals. Photoresists are light-sensitive materials used in photolithography, a process essential for fabricating semiconductor devices. The specific chemical structure of 3,5-Dichlorobenzaldehyde contributes to the desired photochemical properties of certain photoresist formulations, influencing factors like resolution, sensitivity, and etching resistance. As such, reliable access to this intermediate is crucial for companies developing and manufacturing cutting-edge microelectronic components.

Navigating the Procurement Process: Finding a Reliable Supplier

When looking to buy 3,5-Dichlorobenzaldehyde, B2B buyers prioritize manufacturers and suppliers who can guarantee:

  • Consistent Purity: For photoresist applications, even minor impurities can lead to significant defects in semiconductor manufacturing. A supplier's commitment to high purity (often 95% or 99% min) is non-negotiable.
  • Supply Stability: A stable supply chain is vital to avoid production disruptions. Partnering with a manufacturer with substantial production capacity and a robust logistics network ensures you meet your manufacturing schedules.
  • Competitive Pricing: Cost-effectiveness is always a consideration. Obtaining a competitive price for bulk purchases of 3,5-Dichlorobenzaldehyde directly from manufacturers in China can offer significant advantages.
  • Technical Support and Documentation: Access to Certificates of Analysis (COA), Material Safety Data Sheets (MSDS), and responsive technical support is essential for R&D validation and regulatory compliance.
