o-Chlorophenol CAS NO.95-57-8
Product Introduction
o-Chlorophenol is a colorless to pale yellow liquid with a pungent phenolic odor, slightly soluble in water and miscible with organic solvents. It is mainly used as key intermediate for pesticides, dyes, pharmaceuticals and preservatives in fine chemical manufacturing.
o-Chlorophenol (CAS NO.95-57-8) Product Overview
o-Chlorophenol, also known as ortho-chlorophenol, is a colorless to pale yellow aromatic compound with the molecular formula C6H5ClO. It is classified as a phenolic derivative and serves as an important chemical intermediate in the synthesis of pharmaceuticals, agrochemicals, resins, and dyes. Its hydroxyl group positioned ortho to the chlorine atom imparts enhanced reactivity, making it highly valuable for chemical manufacturing and industrial applications. .

FAQ
Q1: What is the purity of your o-Chlorophenol?
A: Our o-Chlorophenol is ≥99% pure, verified through ISO-compliant quality testing.
Q2: Is o-chlorophenol soluble in water?
A: o-Chlorophenol has limited water solubility (approximately 2.8 g/100 mL at 20°C), but is freely soluble in most organic solvents including alcohols, ethers, acetone, and aromatic hydrocarbons. It is also soluble in aqueous alkali solutions due to the acidic phenolic hydrogen (pKa ≈ 8.5).
Q3: What is the main application of o-chlorophenol?
A: The largest application is as a pharmaceutical intermediate for guaifenesin (an expectorant). Other significant uses include intermediates for fungicides, disinfectants, wood preservatives, dye synthesis, and as a precursor for higher chlorinated phenols.
Q4: How should o-chlorophenol be stored?
A: Store in a cool, dry, well-ventilated area away from direct sunlight, heat sources, and oxidizing agents. Keep containers tightly sealed to prevent moisture absorption, oxidation, and volatilization. Shelf life: 24 months from production date.
Q5: Do you offer international shipping?
A: Yes. We provide professional export services, flexible packaging, and global shipping solutions for industrial customers.
Q6: What is the minimum order quantity (MOQ) for o-chlorophenol?
A: One drum (200 kg) for sample evaluation. For regular commercial orders, MOQ is 5 drums (1 metric ton) or one IBC tote (approximately 1.24 metric tons). Bulk ISO tank orders (18-20 metric tons) are available for larger volume requirements.
Q7: What export documents do you provide for o-chlorophenol shipments?
A: Commercial invoice, packing list, Bill of Lading, COA, MSDS, and upon request: Certificate of Origin (C/O), GHS-compliant labels, REACH compliance documentation (for EU shipments), and pharmaceutical grade certificate (if applicable).
