I. Product Introduction

Ethyl mercaptoethanol (also known as mercaptoethane, CAS: 75-08-1), molecular formula C₂H₅SH, is a colorless, transparent, and volatile liquid at room temperature. It has a highly identifiable garlic-like odor, with an odor perception threshold as low as 0.1 ppm, meaning trace amounts are detectable by the human body. It is a mainstream odorant in the global gas industry and a core organic sulfur intermediate in the synthesis of fine chemicals, pesticides, and pharmaceuticals.

Our company mainly deals in 99.0% industrial high-purity grade, 99.5% refined grade, and 99.9% reagent grade ethyl mercaptoethanol. We strictly control impurity content, ensuring batch-to-batch stability and strong antioxidant properties. It is suitable for use in various scenarios including domestic municipal gas, foreign trade export, chemical synthesis, and scientific research experiments. We are a long-term designated supplier for many domestic gas groups, pesticide and pharmaceutical companies, and oil refining enterprises. Core Physicochemical Parameters

II. Mainstream Applications of High-Purity Ethylene Mercaptan

III.Advantages:

1. Stable chemical properties; does not easily decompose under high and low temperature conditions; does not corrode pipes or cause blockages on pipe walls during long-term use; fully complies with domestic gas safety regulations and international odorization standards. 2. Pesticide chemical intermediates: As a core raw material for organophosphorus insecticides and herbicides, used in the synthesis of mainstream agricultural inputs such as phorate, ethion, clethodim, and demeton-methyl; can improve the leaf penetration efficiency of fungicides; is an irreplaceable basic raw material for the production of agricultural chemicals. 3. Pharmaceuticals and fine organic synthesis: Used in the synthesis of anti-tumor, anti-gout, and sulfur-containing antibiotic drugs; serves as a reaction reducing agent and structural modification reagent in laboratory research, mercaptan click chemistry, and the development of organosulfur new materials; high purity ensures repeatable experimental data and stable finished product qualification rate. 4. Petroleum refining and industrial additives: Crude oil desulfurization and purification, heavy metal complexation and precipitation, rubber polymer modification, ore flotation warning gas, fuel antioxidant additives, etc.; suitable for the procurement needs of oil refineries, new material processing plants, and mining enterprises. III. Our Core Advantages as a Professional Supplier

Multiple grades are readily available: Industrial 99%, Refined 99.5%, Ultra-high Purity 99.9%, with customized purification grades available upon request; GC testing throughout the entire process, with each batch accompanied by a quality inspection report, strictly controlling harmful impurities such as sulfides, hydrogen sulfide, and moisture, eliminating inferior raw materials; Direct sourcing of raw materials from large-scale refining plants, eliminating intermediaries, ensuring product oxidation resistance, durability during storage and transportation, and minimal deterioration or ineffectiveness over long-term storage.

Holding a formal hazardous chemicals operation license and hazardous chemicals import/export registration, we can provide normal customs clearance and export services to domestic enterprises, Middle Eastern, Southeast Asian, and South Asian foreign trade clients; Complete documentation: MSDS, COA, commodity inspection documents, hazardous chemical classification identification, and customs declaration documents are provided in one stop, ensuring efficient and smooth customs clearance for foreign trade orders. 3. Stable Inventory + Flexible Delivery: We maintain a constant stock of tens of thousands of tons of goods year-round. Small-batch samples (1kg/5kg), industrial drums (160kg/drum), and large-volume tank truck orders can all be processed quickly, with express delivery within 3 days. We have our own professional hazardous chemical logistics fleet, providing point-to-point delivery nationwide. For international trade, we can handle FOB Qingdao and FOB Shanghai ports, utilizing sea-land combined transport with fully sealed nitrogen-protected packaging to prevent leakage and oxidation during transportation.
