In the intricate world of chemical synthesis, certain molecules stand out for their versatility and importance as building blocks. 5-Chlorosalicylaldehyde (CAS: 635-93-8) is undoubtedly one of them, serving as a crucial intermediate in the development of pharmaceuticals, fragrances, and dyes. For research scientists, product formulators, and procurement managers, understanding the properties and applications of such chemicals is paramount to successful project execution and efficient sourcing.

5-Chlorosalicylaldehyde, also known by synonyms like 2-Hydroxy-5-chlorobenzaldehyde, is characterized by its white to very slightly yellow crystalline powder appearance. Its molecular formula C7H5ClO2 and molecular weight of 156.57 g/mol are standard identifiers. With a melting point typically between 100-102°C, it is a stable solid under ambient conditions, yet sensitive to air, necessitating proper storage to maintain its integrity. The chemical's pKa of 7.73 ± 0.18 hints at its reactivity in various chemical environments.

The primary value of 5-Chlorosalicylaldehyde lies in its utility as an intermediate for organic synthesis. In the pharmaceutical sector, it is a key precursor for synthesizing complex molecules, including those being investigated for therapeutic applications, such as derivatives targeting Alzheimer's disease. Its ability to form stable Schiff bases with amines also makes it a valuable protecting group in peptide synthesis. Procurement managers seeking to buy 5-chlorosalicylaldehyde for their R&D departments can rely on manufacturers who provide high-purity grades, often exceeding 98%. When sourcing, always inquire about the 5-chlorosalicylaldehyde price and availability from reputable suppliers.

Beyond pharmaceuticals, 5-Chlorosalicylaldehyde finds significant use in the fragrance and dye industries. Its structure lends itself to the creation of specific aromatic compounds used in perfumery, contributing unique scent profiles. In the realm of dyes, it acts as a precursor for vibrant and durable colorants utilized across various applications. For companies in these sectors looking for a consistent 5-chlorosalicylaldehyde supplier, partnering with established chemical manufacturers ensures quality and reliability.

Safety is a critical consideration when handling any chemical. 5-Chlorosalicylaldehyde is classified as an irritant, with hazard statements indicating it can cause skin irritation (H315), serious eye irritation (H319), and respiratory irritation (H335). Precautionary measures, such as wearing protective gloves, eye protection, and using it in well-ventilated areas, are essential. Always consult the Material Safety Data Sheet (MSDS) provided by the 5-chlorosalicylaldehyde manufacturer before use.

For businesses aiming to optimize their supply chain, understanding the global market for intermediates like 5-Chlorosalicylaldehyde is key. Several manufacturers and suppliers, particularly in China, offer this compound. When comparing options, consider not just the price but also the purity, lot traceability, and the supplier's technical support. Initiating a quote request with potential suppliers is a proactive step in securing this essential chemical building block for your ongoing projects.
