N-Acetylhomopiperazine

CAS 61903-11-5C7H14N2OHeterocyclic Building Blocks

N-Acetylhomopiperazine (CAS 61903-11-5) is a seven-membered diazepane building block with the molecular formula C7H14N2O and a molar mass of 142.20 g/mol. It is the mono-acetylated derivative of homopiperazine (1,4-diazepane), supplied at a typical assay of at least 97.0% (GC) as a research-grade reagent. With one ring nitrogen protected as an acetamide and the other left free, it serves as a versatile intermediate in pharmaceutical and fine-chemical synthesis. Tech Serve Solutions supplies and exports it worldwide.

01 /Applications

Heterocyclic building block

Used as a C4-to-C8 diazepane scaffold in chemical synthesis, providing a homopiperazine ring with one nitrogen pre-protected as an acetyl group. This selectivity supports controlled functionalisation of the remaining free secondary amine.

Pharmaceutical intermediate

Serves as an intermediate in the preparation of biologically active molecules built on the homopiperazine (1,4-diazepane) motif, a ring system widely employed in medicinal-chemistry programmes. Tech Serve Solutions supplies it for research and manufacturing use.

Protected amine handle

The acetyl group acts as a temporary protecting group on one ring nitrogen, allowing the free amine to undergo alkylation, acylation or reductive amination before the acetamide is removed under standard conditions.

Research and discovery chemistry

Suitable as a reagent and reference compound for laboratory-scale exploratory synthesis, structure-activity studies and route-development work involving substituted diazepanes.
