5-Dihydroxytoluene (commonly known as Orcinol, CAS: 504-15-4, IUPAC: 5-methylbenzene-1,3-diol) is an organic phenolic compound characterized by a benzene ring substituted with two hydroxyl groups at positions 1 and 3, and a methyl group at position 5. Structurally recognized as a methylated resorcinol derivative, it functions as a crucial structural block in specialized chemical synthesis.
As premier China 5-Dihydroxytoluene Manufacturers & Suppliers, JIMPOCHEM provides ultra-pure grade Orcinol engineered for demanding applications across cosmetic skin-lightening precursors, diagnostic carbohydrate reagents, advanced dyes, and pharmaceutical building blocks.

How JIMPOCHEM leverages scalable continuous-flow micro-reactors to achieve high yield, low impurity profile, and environmental sustainability.
Traditional manufacturing routes start from toluene through controlled disulfonation to produce toluene-3,5-disulfonic acid, followed by high-temperature sodium hydroxide fusion. JIMPOCHEM has modernized this pathway by introducing high-efficiency catalysts, significantly reducing side-product formation such as cresols and polyphenolic tars.
Utilizing state-of-the-art continuous flow micro-reactors in our Shandong production hub, we achieve precise control over reaction kinetics, exothermic heat transfer, and residence times. This technical advancement guarantees batch-to-batch consistency and ensures heavy metal contaminants remain strictly under 5 ppm.
Adhering to China's strict environmental policies and international ESG criteria, our facility employs closed-loop solvent recovery units and biological wastewater treatment systems. Mother liquors are recycled to minimize carbon footprint while securing continuous bulk volume availability for global buyers.
Market dynamics, supply chain integration, and regional demand drivers shaping the 5-Dihydroxytoluene ecosystem.
The global demand for phenolic intermediates has shifted rapidly toward vertically integrated Chinese manufacturers. With direct access to upstream petrochemical feedstock (toluene, sulfur trioxide, caustic soda) within the Jinan Chemical Industry Park, JIMPOCHEM offers an resilient supply structure immune to raw material volatility.
Our strategic buffer stocks in major logistics hubs enable fast sea and air shipping to North America, Europe, East Asia, and the Middle East, minimizing inventory holding costs for downstream formulators.
Unlocking functional performance across dermatology, life sciences, polymers, and fine chemical synthesis.
In modern skincare science, substituted resorcinols represent the gold standard for controlling melanin synthesis. 5-Dihydroxytoluene serves as the key molecular scaffold for synthesizing tailored alkylresorcinol analogs. These compounds demonstrate high binding affinity to the active site of the tyrosinase enzyme, delivering superior skin whitening efficiency compared to hydroquinone without cytotoxicity issues.
Orcinol (5-Dihydroxytoluene) combined with ferric chloride and concentrated hydrochloric acid forms Bial's Reagent. When reacted with pentose sugars (such as ribose in RNA), it forms a characteristic bluish-green complex measurable via spectrophotometry. Pharmaceutical research labs rely on our ultra-pure analytical grade (Assay ≥99.5%) for quantitative nucleic acid assays.
Within polymer matrix engineering, 5-Dihydroxytoluene functions as an effective chain-breaking phenolic antioxidant, protecting synthetic resins from thermo-oxidative degradation. Furthermore, it acts as an essential intermediate for xanthene dyes, fluorescent probes, and histology staining agents used in biological microscopy.

Addressing key technical, procurement, and commercial queries for prospective global buyers.
Standard Resorcinol (1,3-dihydroxybenzene) lacks a methyl substituent on the benzene ring. 5-Dihydroxytoluene (Orcinol) contains an additional methyl group at position 5 (5-methylbenzene-1,3-diol). This additional methyl group alters its lipophilicity, reaction kinetics, and specific steric interactions, making it ideal for target active precursors like 4-alkylresorcinols and specialized diagnostic reagents where standard resorcinol gives different colorimetric outputs.
Phenolic compounds are inherently sensitive to oxygen and moisture, which can cause subtle pinkish or brownish surface discoloration over time. JIMPOCHEM packages 5-Dihydroxytoluene under nitrogen purging in heavy-duty double PE inner bags, sealed inside moisture-impermeable aluminum-lined vacuum barriers and enclosed in rigid fiber drums. This packaging system guarantees color stability even during extended ocean transit across high-humidity climate zones.
For biochemical pentose determination and RNA analytical verification, we recommend our Analytical Grade Orcinol with an HPLC assay of ≥99.5%. Lower purity grades containing trace isomers or heavy metals can cause background absorbency interference at the 660 nm UV-Vis wavelength, distorting quantitative colorimetric calculations.
