Tetramethylethylenediamine Overview

Tetramethylethylenediamine (TMEDA; N,N,N’,N’-tetramethylethylenediamine; CAS 110-18-9) is a bidentate tertiary diamine widely used across fine chemicals and catalyst applications as a ligand, promoter, and process aid. With the chemical formula C6H16N2 and a typical boiling point around 121–122°C, TMEDA is valued for its strong metal-chelating ability and ability to tune reactivity in organometallic systems. In practice, it helps unlock faster reaction rates, improved selectivity, and higher throughput in demanding synthesis routes. Typical specifications for commercial-grade TMEDA include high assay (often ≥99%), low moisture, low color, and tight control of trace impurities to minimize catalyst poisoning. Physical properties such as density near 0.77–0.78 g/cm³ (20–25°C) and a refractive index around 1.405 support predictable in-plant handling and metering.

• As a versatile diamine ligand, Tetramethylethylenediamine enhances performance in catalytic cross-couplings, metalations, and polymerization-related workflows, supporting consistent scale-up from kilo to plant scale.
• Technical users value TMEDA for enabling cleaner conversions, stabilizing reactive intermediates, and facilitating homogeneous catalyst systems.
• Shijiazhuang Sincere Chemicals Co., Ltd. supplies TMEDA with robust QC, full documentation (COA/SDS), and reliable packaging options to meet B2B production needs globally.

Benefits & Use Cases of Tetramethylethylenediamine in catalyst

In catalyst-focused environments, Tetramethylethylenediamine operates as a high-utility ligand and promoter. In copper-catalyzed transformations (e.g., C–N/C–O bond formations), TMEDA supports efficient coordination, helping catalysts reach higher turnover frequencies and improved selectivity. In organolithium and Grignard chemistry, TMEDA coordinates metal centers to enhance reagent reactivity, enabling cleaner metalations upstream of catalytic steps—a benefit for pharmaceutical and agrochemical intermediate synthesis. In polymerization-related processes, TMEDA can accelerate anionic polymerizations and help control molecular weight distribution by coordinating with alkali metals, improving batch-to-batch consistency.

• Application breadth: homogeneous catalysis, cross-coupling workflows, and anionic polymerization setups in fine chemical plants.
• Competitive advantages: high purity reduces catalyst deactivation; predictable chelation delivers reproducible rates and selectivity; low moisture supports sensitive metal systems.
• Shijiazhuang Sincere Chemicals Co., Ltd. provides technical support for integration, helping B2B teams optimize dosage, solvent choices, and handling to fit their catalyst platforms.

Cost, Maintenance & User Experience

Total cost of ownership for Tetramethylethylenediamine hinges on purity consistency, logistics reliability, and process efficiency gains. High-spec TMEDA helps reduce cycle times, rework, and waste through more reliable catalytic performance—improving ROI across multi-step synthesis. Shijiazhuang Sincere Chemicals Co., Ltd. supports economic delivery via fit-for-purpose packaging, such as HDPE drums and IBCs, to minimize losses and streamline charging. Clear COA parameters (assay, water, color, residue) and batch-to-batch traceability help QA/QC teams maintain compliant operations and lower the cost of deviation management.

• Durability and handling: store sealed in a cool, dry, well-ventilated area; protect from moisture; nitrogen blanketing is often recommended for sensitive applications. Compatible with stainless-steel transfer systems and standard amine-rated elastomers.
• User experience: production teams note smoother starts in organometallic steps, steadier catalyst performance, and improved downstream purification when moisture and impurities are tightly controlled.

Sustainability & Market Trends in chemical industry

Catalyst and fine-chemical manufacturers are prioritizing efficiency, greener solvents, and lower energy footprints. As a versatile diamine ligand, Tetramethylethylenediamine can help enable milder conditions and cleaner conversions—supporting reduced energy demand and waste generation. Regulatory expectations around safe handling, transparent documentation, and responsible supply are rising globally. Buyers now evaluate suppliers not only on price and purity, but also on consistency, data access, and environmental stewardship across the value chain.
