Product Description
Our o-Cresol is a high-purity industrial-grade phenolic monomer with 99.5% GC purity. o-Cresol (CAS 95-48-7), also known as 2-Methylphenol , is a basic ortho-substituted methylphenol compound. It features a unique methyl and phenolic hydroxyl dual-active structure, with higher reaction activity and better cross-linking performance than ordinary phenol. Different from Guaiacol (methoxy-substituted, flavor-focused) and vanilla-series derivatives (Vanillin, Vanillyl Alcohol, skincare & flavor-oriented), o-Cresol is positioned as a high-performance industrial synthetic monomer, focusing on resin modification, surfactant synthesis, pesticide and pharmaceutical intermediate preparation, forming a differentiated industrial phenolic raw material system. As a professional bulk o-Cresol supplier, we provide low-impurity, high-activity, thermally stable o-Cresol raw materials for global fine chemical factories, new material enterprises and pharmaceutical synthesis institutions.
o-Cresol belongs to the cresol isomer family, with clear functional differentiation from other phenolic products. Compared with Guaiacol which has natural aroma and flavor tuning advantages, o-Cresol has stronger chemical reactivity and polymerization ability. Its ortho-methyl structure effectively improves the toughness, heat resistance and curing speed of phenolic resins, making it irreplaceable in high-temperature resistant resin and insulating material synthesis. Unlike cosmetic and food-grade phenolic active ingredients, o-Cresol focuses on industrial synthesis value, with stable molecular structure, high conversion rate in downstream reactions, and excellent batch stability, being a core basic raw material in the fine chemical industry chain.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium o-Cresol adopts crude phenol fractionation and multi-stage high-vacuum precision distillation purification technology. We strictly separate m-cresol, p-cresol and other isomer impurities, completely remove heavy metal residues, tar components and unreacted miscellaneous materials, and fully retain the pure ortho-methylphenol active structure. The whole production process complies with fine chemical grade standards, effectively solving the problems of low purity, high isomer impurity content and unstable curing activity of ordinary industrial o-Cresol. The finished product has uniform crystal state, low moisture content and excellent chemical stability, ensuring efficient and stable application in various industrial synthesis scenarios.
Every batch of o-Cresol undergoes strict multi-dimensional quality inspection, including GC high-precision purity detection, isomer content analysis, NMR structural verification and mass spectrometry molecular identification to ensure accurate molecular structure and ultra-low impurity residual. The product appears as colorless transparent crystals, with pure phenolic odor, good solubility in organic solvents and strong reaction activity. All indicators meet international industrial fine chemical specifications, supporting standardized and safe use in resin synthesis, surfactant modification, pharmaceutical and pesticide intermediate production.
We maintain sufficient inventory and complete qualification documents for bulk o-Cresol supply. Whether you need high-activity curing monomers for modified phenolic resins, basic raw materials for surfactant and chemical additive synthesis, or standard high-purity intermediates for pharmaceutical and pesticide research, our o-Cresol is a cost-effective and high-value industrial phenolic raw material choice for global buyers.
