Q1: What is the CAS Registry Number for N,N-Dimethyl-1,3-propanediamine?
A: The CAS number is 109-55-7. Our semiconductor-grade material undergoes additional purification to achieve ≥99.999% purity with verified trace metal certification.
Q2: What is the recommended handling concentration for use in ALD precursor formulation?
A: Typical molar ratios range from 1.2:1 to 2.5:1 (amine:metal precursor), depending on target volatility and film carbon residue. Dilution in anhydrous toluene or hexanes is advised under inert atmosphere.
Q3: How does this specialty amine differ from standard commercial N,N-dimethyl-1,3-propanediamine?
A: Unlike commodity grades, our product features sub-ppb sodium/potassium, <1 ppb Fe/Al/Cu, certified absence of chloride and sulfate ions, and full traceability via lot-specific CoA aligned with SEMI F57.
Q4: Is this material subject to migration or leaching in post-deposition thermal processing?
A: No significant migration is observed below 350°C in SiO₂ or SiNₓ matrices. TGA-MS data confirms clean decomposition onset at 215°C with >99.5% volatile removal by 300°C—no detectable amine residue in SIMS depth profiling.
