Specification

Application

1. Pharmaceutical intermediates: for the synthesis of antibacterial drugs, herbicides, and molecular structural blocks of drugs.

2. Dye intermediates: for the synthesis of azo dyes and functional organic dyes, used for fabric dyeing.

3. Coatings, personal care products, preservatives and disinfectants, used as coating preservatives and antibacterial raw materials.

4. High molecular materials: for the preparation of ion exchange resins and special plasticizers, and for the synthesis of polyester-based polymers.

5. Organic synthesis raw materials, 3-Hydroxybenzoic acid used in fine chemicals and the synthesis of fragrances and flavors.

Our advantages

• 1. Dual-functional aromatic building blocks, containing both hydroxyl and carboxyl groups, can undergo various reactions such as esterification, etherification, and acylation, generating a large number of downstream fine chemicals and offering multiple synthesis route options.
• 2. Stable purity, industrial grade ≥ 99%, with strict control of moisture ≤ 0.3% and ash content ≤ 0.3%, ensuring batch consistency and reducing by-products, thereby increasing the downstream reaction yield.
• 3. Excellent stability, high melting point, and resistance to decomposition under high-temperature reaction conditions, making it suitable for high-temperature condensation and esterification processes.
• 4. Solubility characteristics: easily soluble in hot water, ethanol, and ether; slightly soluble in cold water, insoluble in benzene. This facilitates customers’ selection of solvent systems based on their processes.
• 5. Wide application fields, covering pharmaceuticals, dyes, coatings and anti-corrosion, high-molecular resins, etc., with stable market demand.
• 6. Ordinary chemical exports, with simple procedures; complete export materials including MSDS and COA are provided; stable factory supply, and customizable packaging is available.

Packaging

25kg/drum or according to customer requirements.

FAQ

Q: How about its solubility?
A: It is easily soluble in hot water, ethanol, and ether; slightly soluble in cold water, and insoluble in benzene and petroleum ether.

Q: What are the storage conditions and shelf life?
A: Store in a sealed, cool, dry, and ventilated warehouse away from light, and keep away from oxidants and strong bases. The original packaging is sealed and has a shelf life of 24 months. This product is stable and does not easily decompose under normal storage conditions.

Q: What is the recommended packaging method? MOQ & delivery time?
A: 25kg cardboard drums (with PE inner bags). MOQ: 25kg; available for delivery within 3-7 days for regular orders, and production can be arranged for large orders.

Q: Can it be directly added as a preservative to personal care products?
A: Generally, it is not added as a preservative for finished products directly. It is more often used as an intermediate in synthetic preservatives. Customers need to confirm the personal care regulations of the target country before using it.
