For professionals in the chemical industry, a deep understanding of the properties and applications of key raw materials is crucial for successful sourcing and product development. 2,5-Dihydroxybenzoic Acid, identified by its CAS number 490-79-9 and also known as Gentisic Acid, is a significant chemical intermediate with a range of valuable uses across different sectors, including pharmaceuticals, cosmetics, and potentially in food applications. This article aims to provide buyers with essential information to make informed decisions when considering a purchase.

Chemically, 2,5-Dihydroxybenzoic Acid is an organic compound characterized by a benzene ring substituted with two hydroxyl (-OH) groups and one carboxylic acid (-COOH) group. Its common appearance is a white to light yellow crystalline solid, which is often readily soluble in water due to the polar nature of its functional groups. This chemical structure is the basis for its utility as a building block in organic synthesis and for its inherent properties, such as antioxidant activity. Buyers will often look for specific quality standards like USP, BP, or FCC depending on their intended application, necessitating a clear understanding of supplier capabilities.

The applications of 2,5-Dihydroxybenzoic Acid are diverse. In the pharmaceutical industry, it serves as a vital intermediate for synthesizing Active Pharmaceutical Ingredients (APIs) and can also function as an antioxidant excipient, contributing to the stability of formulations. Cosmetic formulators utilize its antioxidant properties to enhance skincare products, protecting against oxidative stress and degradation. Its potential use in the food industry as an additive also broadens its market appeal. For businesses aiming to buy CAS 490-79-9, identifying a manufacturer that offers these various grades is a key step.

When seeking to purchase 2,5-Dihydroxybenzoic Acid, especially in bulk quantities like the standard 25kg drums, it is important to engage with reliable suppliers. China has become a central hub for the production of fine chemicals, offering competitive pricing and large-scale manufacturing capabilities. Companies like NINGBO INNO PHARMCHEM CO.,LTD. are recognized suppliers, providing consistent quality and efficient service. Buyers should always inquire about the latest pricing, minimum order quantities, and lead times to ensure their procurement aligns with their production schedules.

Ultimately, understanding the chemical properties and application spectrum of 2,5-Dihydroxybenzoic Acid empowers buyers to select the right product and the most suitable supplier. For those needing to buy CAS 490-79-9, a focus on purity standards, supplier reliability, and competitive pricing will lead to a successful and productive partnership, supporting innovation and manufacturing excellence across industries.
