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
¿Cuál es la cantidad mínima de pedido (MOQ) para TMEDA?
El MOQ depende del grado acordado, el embalaje, el estado del stock, el destino y los requisitos del proyecto. Por favor, comparta su cantidad requerida y la aplicación prevista para que TUODA pueda confirmar la cantidad mínima de pedido actual y el tamaño de paquete adecuado antes de la cotización.
¿Puedo solicitar una muestra antes de realizar un pedido al por mayor?
Puede haber muestras disponibles para proyectos de evaluación calificados. Proporcione la aplicación prevista, la cantidad solicitada, el destino y las necesidades de documentación; el tamaño de la muestra, el cargo, el flete y la disponibilidad de COA/SDS se confirmarán para el grado TMEDA solicitado.
¿Puede TUODA personalizar la pureza o el empaque de TMEDA según mis requisitos?
TUODA puede revisar la pureza solicitada, el empaque, el etiquetado y los parámetros de calidad acordados, sujeto al grado suministrado y a la capacidad operativa actual. Confirme la especificación requerida, el contenedor, el idioma de la etiqueta, el destino y los requisitos aplicables antes de la producción o el envío.
¿Está la TMEDA clasificada como mercancía peligrosa para el envío?
La clasificación de transporte y los requisitos de envío deben confirmarse a partir de la SDS específica del grado actual, la configuración del paquete, la ruta y las reglas del país de destino. No asuma una clasificación universal; TUODA revisará la documentación de transporte disponible para el pedido específico antes del envío.
¿Qué certificaciones y documentación ofrecen?
Para proyectos cualificados, TUODA puede proporcionar una especificación acordada, COA, SDS/MSDS, TDS e información de embalaje disponible. Cualquier certificación, declaración o documento reglamentario debe ser confirmado para el grado específico, destino y uso previsto antes de la compra.
¿Cómo se debe almacenar TMEDA en el sitio?
Mantenga el producto sellado en un área fresca, seca y bien ventilada, lejos del calor, fuentes de ignición y materiales incompatibles. Siga la SDS vigente, la etiqueta del producto suministrado y los procedimientos de gestión química de su sitio.
¿Qué tan rápido puedes enviar TMEDA?
Los plazos de entrega de muestras y pedidos al por mayor dependen del estado del stock, las especificaciones, el embalaje, la cantidad del pedido, los documentos de exportación y el destino. Comparta estos detalles con TUODA para obtener una estimación actual de producción y envío; no confíe en un plazo de entrega fijo.
¿Proporcionan apoyo regulatorio y técnico?
TUODA puede respaldar discusiones sobre información del producto, especificaciones, COA, SDS/MSDS, TDS y documentos de exportación para proyectos B2B calificados. El diseño del proceso, las presentaciones regulatorias y el cumplimiento de la aplicación final siguen siendo responsabilidad del cliente y de los especialistas correspondientes.
