Product Description
Our m-Cresol is a high-purity industrial-grade meta-isomer phenolic monomer with 99.5% GC purity. m-Cresol (CAS 108-39-4), also known as 3-Methylphenol , is a critical isomer in the cresol series. Featuring a unique meta-methyl substituted phenolic structure, it possesses completely different physical and chemical properties from o-Cresol and p-Cresol. Unlike ortho-cresol which focuses on resin curing and cross-linking modification, m-Cresol excels in high-performance polymer dissolving capacity and high-selectivity organic synthesis, serving as a professional polymer solvent and high-value fine chemical intermediate. It is widely used in conductive polymer film preparation, medical antiseptic synthesis, vitamin E production and pesticide intermediate manufacturing, forming a highly differentiated industrial application system in the cresol product family. As a reliable bulk m-Cresol supplier, we provide low-impurity, high-selectivity, stable-quality m-Cresol raw materials for global new material factories, pharmaceutical enterprises and fine chemical manufacturers.
m-Cresol has irreplaceable industrial advantages among cresol isomers. Its meta-methyl structure endows it with superior solubility for special polymers such as polyaniline, polyimide and thermoplastic resins, enabling the production of high-conductivity and high-stability polymer film materials that cannot be achieved by other cresol isomers. In terms of synthesis activity, m-Cresol exhibits higher reaction selectivity in methylation, nitration and condensation reactions, which is the exclusive core raw material for synthesizing high-purity 2,3,6-trimethylphenol, the key precursor of synthetic vitamin E. Meanwhile, it retains excellent broad-spectrum bactericidal and antiseptic properties, supporting the production of medical antiseptic ingredients such as amylmetacresol. Compared with vanilla-series phenolic products focused on flavor and skincare, m-Cresol is purely industrial-oriented, highlighting new material solvent and high-end intermediate value.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium m-Cresol adopts crude phenol fractional distillation and multi-stage high-vacuum precision purification technology. We precisely separate o-cresol, p-cresol and other impurity isomers, completely remove tar residues, heavy metals and non-phenolic impurities, and fully retain the pure meta-methylphenol active structure. The whole production process strictly complies with fine chemical grade standards, solving the common defects of mixed isomers, poor solubility and low synthesis selectivity of ordinary industrial m-Cresol. The finished product features transparent and uniform liquid state, mild pure phenolic odor, stable chemical properties and excellent batch consistency, fully meeting the strict raw material requirements of new material preparation and pharmaceutical synthesis.
Every batch of m-Cresol undergoes strict multi-dimensional quality inspection, including GC high-precision isomer purity analysis, NMR structural identification and mass spectrometry molecular verification to ensure ultra-high single-isomer purity and zero invalid impurity interference. The product has excellent organic solvent compatibility, stable low-volatility performance and high reaction activity, fully compliant with international industrial fine chemical and pharmaceutical auxiliary material standards. It supports stable and efficient application in high-end polymer material preparation, medical antiseptic production, vitamin synthesis and fine chemical derivation.
We maintain sufficient inventory and complete qualification documents for bulk m-Cresol supply. Whether you need high-efficiency special polymer solvents for new material research, high-selectivity intermediates for vitamin E and pesticide synthesis, or standard raw materials for medical antiseptic manufacturing, our high-purity m-Cresol is a cost-effective and high-value industrial phenolic raw material choice for global buyers.
