1-(2-Hydroxyethyl)piperidine

CAS 3040-44-6C7H15NOChemical Synthesis

1-(2-Hydroxyethyl)piperidine (CAS 3040-44-6) is a tertiary amino alcohol with the molecular formula C7H15NO and a molar mass of 129.20 g/mol. Also known as 1-piperidineethanol, it is a clear liquid combining a saturated piperidine ring with a pendant 2-hydroxyethyl group. This bifunctional reactivity makes it a versatile heterocyclic building block in chemical synthesis, particularly for pharmaceutical intermediates and fine-chemical research. Tech Serve Solutions supplies it at 99% assay to laboratory and manufacturing customers worldwide.

01 /Applications

Pharmaceutical and fine-chemical intermediate

Serves as a piperidine-based amino alcohol building block in the synthesis of active pharmaceutical ingredients and other fine chemicals. The secondary hydroxyl and tertiary amine offer convenient handles for alkylation, acylation and substitution chemistry.

Heterocyclic building block

Used to introduce the piperidinoethanol motif into more complex molecules. It is a common reagent for constructing N-substituted piperidine scaffolds in medicinal and exploratory chemistry.

Organic synthesis reagent

Functions as a tertiary amine base and nucleophile, and as a hydroxyethyl-bearing reactant for esterification, etherification and condensation reactions. Its dual functionality supports a broad range of laboratory transformations.

Research and development

Supplied at 99% assay for method development, structure-activity studies and small-scale process work where a defined, reproducible piperidine amino alcohol is required.
