1-(2-Methoxyethyl)-6-oxopiperidine-3-carboxylic acid
1-(2-Methoxyethyl)-6-oxopiperidine-3-carboxylic acid (CAS 915920-08-0; C9H15NO4; molar mass 201.22 g/mol) is a functionalised heterocyclic building block. Structurally it is a 2-piperidinone (delta-valerolactam) carrying a carboxylic acid at the 3-position and an N-linked 2-methoxyethyl group, giving a compact, polar scaffold. Tech Serve Solutions supplies it as a research-grade fine chemical for synthetic chemistry, where its lactam, acid and ether handles make it useful in medicinal-chemistry and process-development programmes.

Heterocyclic building block
Serves as a saturated piperidinone (piperidone) scaffold in synthetic chemistry. The pre-installed lactam ring and substituents provide a defined three-dimensional core for constructing more complex molecules.
Pharmaceutical intermediate
Used as an intermediate in medicinal-chemistry and discovery research. Piperidinone carboxylic acids of this type are common starting points for analogue libraries and structure-activity studies.
Carboxylic acid handle for derivatisation
The 3-carboxylic acid group offers a reactive site for amide coupling, esterification and salt formation, enabling onward functionalisation and conjugation.
Polar, soluble scaffold for medicinal chemistry
The N-(2-methoxyethyl) ether and the lactam add polarity to the ring system, a property often exploited to modulate solubility and physicochemical behaviour during lead optimisation.
Laboratory and reference use
Supplied for laboratory-scale synthesis and method-development work where a well-defined, single-compound building block is required.
