Product Introduction
Product Overview
A chelating diamine for controlled organometallic and pharmaceutical-intermediate workflows
N,N,N’,N’-Tetramethylethylenediamine (TMEDA), CAS 110-18-9, is a tertiary diamine ligand used to coordinate metal centers and modify reactivity in selected organometallic processes.
It is commonly evaluated with organolithium and Grignard reagents, as well as in selected metalation, complexation and fine-chemical workflows. Suitability must be confirmed for the intended process.
TMEDA is flammable. Use requires trained personnel, compatible equipment, suitable ventilation and site procedures based on the current SDS. TUODA can provide agreed specifications, COA, SDS/MSDS, TDS and packaging information for qualified B2B projects.

FAQ
Frequently Asked Questions
What’s the Minimum Order Quantity (MOQ) for TMEDA?
MOQ depends on the agreed grade, packaging, stock status, destination and project requirements. Please share your required quantity and intended application so TUODA can confirm the current minimum order quantity and suitable pack size before quotation.
Can I Request a Sample Before Placing a Bulk Order?
Samples may be available for qualified evaluation projects. Please provide the intended application, requested quantity, destination and documentation needs; sample size, charge, freight and COA/SDS availability will be confirmed for the requested TMEDA grade.
Can TUODA Customize the Purity or Packaging of TMEDA Based on My Requirements?
TUODA can review requested purity, packaging, labeling and agreed quality parameters subject to the supplied grade and current operational capability. Confirm the required specification, container, label language, destination and applicable requirements before production or shipment.
Is TMEDA Classified as a Dangerous Good for Shipping?
Transport classification and shipment requirements must be confirmed from the current grade-specific SDS, package configuration, route and destination-country rules. Do not assume a universal classification; TUODA will review the available transport documentation for the specific order before shipment.
What Certifications and Documentation Do You Offer?
For qualified projects, TUODA can provide an agreed specification, COA, SDS/MSDS, TDS and available packaging information. Any certification, statement or regulatory document must be confirmed for the specific grade, destination and intended use before purchase.
How Should TMEDA Be Stored On-Site?
Keep the sealed product in a cool, dry, well-ventilated area away from heat, ignition sources and incompatible materials. Follow the current SDS, supplied product label and your site’s chemical-management procedures.
How Fast Can You Ship TMEDA?
Sample and bulk lead times depend on stock status, specification, packaging, order quantity, export documents and destination. Share these details with TUODA for a current production and shipping estimate; do not rely on a fixed delivery window.
Do You Provide Regulatory and Technical Support?
TUODA can support product-information, specification, COA, SDS/MSDS, TDS and export-document discussions for qualified B2B projects. Process design, regulatory submissions and final application compliance remain the responsibility of the customer and relevant specialists.
