Diallyldimethylammonium Chloride (DADMAC) CAS 7398-69-8

FAQ - Technical & Supply Chain

• Q:

  Are DADMAC and Diallyldimethylammonium Chloride the same monomer?

  A: Yes. DADMAC, DMDAAC and diallyldimethylammonium chloride all identify the quaternary ammonium monomer with CAS 7398-69-8 and molecular formula C8H16ClN. Do not confuse it with polyDADMAC, the cationic polymer made from this monomer, which has a different polymer CAS and much higher molecular weight.
• Q:

  What is DADMAC used for?

  A: It is mainly polymerized into polyDADMAC or copolymers for water treatment coagulants and flocculants, papermaking, textiles, antistatic finishes, adhesives, personal care formulations, oilfield chemistry, mining and mineral recovery. The end-use polymer and charge demand should determine the suitable monomer grade and concentration.
• Q:

  Which specifications should be agreed for industrial DADMAC?

  A: Confirm active DADMAC content, appearance, pH, chloride or sodium chloride limit, APHA colour, polymer content and any residual allyl or inhibitor specification. For aqueous grades, also agree concentration, density and the exact test basis so different offers can be compared on the same terms.
• Q:

  What form and concentration should be specified?

  A: Commercial DADMAC is commonly supplied as a colorless to light-yellow aqueous solution, often around 60% or 65% active content, rather than as a neat solid. Specify the physical form and active-content basis in the polymerization recipe, then compare quotations only after normalizing concentration, inhibitor level and impurities.
• Q:

  How should DADMAC be stored and handled?

  A: Keep it in a cool, dry place protected from moisture and direct heat, and avoid damage or leakage of drums or IBCs during loading and unloading. The monomer contains polymerizable allyl groups, so protect it from unintended polymerization conditions and confirm inhibitor level and storage temperature for the specific offered grade.
• Q:

  What should be confirmed before requesting a DADMAC quotation?

  A: Confirm the exact monomer identity, required aqueous concentration or other physical form, intended polymer or application, packaging volume and destination requirements. Also confirm the current product-specific specification, inhibitor type and storage advice for the offered material before comparing suppliers.
