N33dimethylbutylLaspartylLphenylalanine

I’m having trouble identifying a widely recognized chemical or topic named “N33dimethylbut...”. It doesn’t map to a standard IUPAC name or a common abbreviation I’m aware of, so I’m not able to produce a reliable wiki-style article without clarification.

If you intended one of the following, I can draft a concise entry accordingly (or you can provide the exact term):

- N,N-dimethylbutan-1-amine (a tertiary amine used as a solvent or intermediate)

- N,N-dimethylbutanamide (a tertiary amide)

- N-3,3-dimethylbutylamine or a related N-substituted butyl amine

- A different compound with a similar name or a typographical error

Please provide the correct name (or a brief description of the compound’s structure, function, or context), and I will generate a neutral, informative wiki-style article under 300 words.
