For research and development scientists, access to well-characterized chemical intermediates is fundamental to driving innovation. 4-Chlorosalicylaldehyde (CAS: 2420-26-0), also known as 4-Chloro-2-hydroxybenzaldehyde, is a prime example of such a compound, serving as a critical building block in various organic synthesis projects. This article aims to provide R&D professionals with a comprehensive overview of its properties and essential considerations for sourcing.

Chemically, 4-Chlorosalicylaldehyde is an aromatic aldehyde characterized by the presence of a hydroxyl group and a chlorine atom on the benzene ring. Its molecular formula is C7H5ClO2, and it has a molecular weight of approximately 156.57 g/mol. Typically supplied as a light yellow powder, its physical properties include a melting point around 47°C, though variations exist depending on purity. The CAS registry number, 2420-26-0, is the universal identifier used globally to reference this chemical. Purity levels commonly available range from 95% to upwards of 98%, with higher purity grades being preferred for more sensitive research applications to ensure predictable reaction outcomes.

The utility of 4-Chlorosalicylaldehyde in R&D is extensive. It is frequently employed as a key intermediate in the synthesis of pharmaceuticals, contributing to the creation of complex molecular structures. Researchers are also exploring its derivatives for potential therapeutic benefits, including in studies related to neurodegenerative diseases. Furthermore, its role in the development of dyes, fragrances, and specialty materials highlights its broad applicability across chemical disciplines. Scientists looking to buy 4-chlorosalicylaldehyde for their research endeavors should prioritize suppliers who can offer detailed specifications and certificates of analysis.

When sourcing for research purposes, consider the supplier's reputation and the ease of procurement. Many global chemical suppliers offer 4-Chlorosalicylaldehyde, with competitive pricing often available for smaller research quantities. However, it is always wise to obtain multiple quotes and compare the 4-chlorosalicylaldehyde price from various sources. Establishing a relationship with a reliable 4-chlorosalicylaldehyde supplier that can also assist with technical inquiries can be highly beneficial for ongoing research projects.

For effective sourcing, R&D managers and scientists should pay close attention to packaging, storage conditions (generally cool, dry, and protected from light/air), and safety data. The chemical is classified as an irritant, requiring appropriate personal protective equipment and handling procedures. Understanding these aspects upfront will facilitate smoother integration of 4-Chlorosalicylaldehyde into your laboratory's workflow. By meticulously evaluating potential suppliers and understanding the compound's specific properties, R&D teams can ensure they are well-equipped with this vital chemical intermediate.
