Industrial Overview: 4-Oxo-Piperidine-1-Carboxylic Acid Ethyl Ester

4-Oxo-piperidine-1-carboxylic acid ethyl ester (also recognized under CAS Registry Numbers 90315-82-5 and 56311-79-2, chemical formula C8H13NO3) is a cornerstone aliphatic heterocycle used extensively across the modern synthetic landscape. Featuring a piperidone ring protected by an N-carbethoxy group, this bifunctional keto-ester serves as an indispensable scaffold for complex pharmaceutical intermediates, central nervous system (CNS) active pharmaceutical ingredients (APIs), oncology agents, and advanced agrochemicals.

In global chemical synthesis, maintaining structural integrity while achieving high regioselectivity during condensation, amination, or reduction reactions requires ultra-pure starting materials. China's industrial manufacturing ecosystem for 4-oxo-piperidine-1-carboxylic acid ethyl ester has advanced rapidly, moving from basic batch chemistry to continuous-flow hydrogenation and automated crystallization tech. As top-tier exporters, China factories provide reliable commercial volume, minimal lot-to-lot variance, and compliance with stringent Western regulatory frameworks (including REACH, cGMP, and US FDA DMF requirements).

Key Chemical Identification & Technical Specifications:
  • IUPAC Name: Ethyl 4-oxopiperidine-1-carboxylate
  • CAS Number: 90315-82-5 / 56311-79-2
  • Molecular Weight: 171.19 g/mol | Formula: C8H13NO3
  • Purity Profile: Commercial Grade ≥98.5%; High-Purity API Grade ≥99.5% (GC)
  • Appearance: Clear pale yellow to colorless liquid / low-melting solid
  • Key Impurity Limits: Single Individual Impurity ≤ 0.2%, Water Content (KF) ≤ 0.1%

Global Market Dynamics & Procurement Demand Drivers

The international demand for 4-oxo-piperidine-1-carboxylic acid ethyl ester is driven by the expansion of targeted neuro-therapeutics, metabolic disease research, and small-molecule drug development. As drug discovery pipelines shift toward rigid, 3D heterocycles to improve drug-like properties (such as sp3-carbon character and metabolic stability), N-protected piperidone derivatives have emerged as key synthons.

Pharmaceutical purchasing agents in North America, Western Europe, and Japan require chemical vendors capable of delivering high volume with detailed analytical documentation (HPLC, 1H-NMR, GC-MS, ICP-MS trace metals analysis). Chinese manufacturers lead this market segment by offering high cost-efficiency, continuous raw material integration, and robust QA/QC oversight.

Region Primary Application Sectors Demand Trend (2024-2030) Key Regulatory Compliance Required
North America Pharmaceutical APIs, Custom Peptide Synthesis, CNS Drugs High Growth (CAGR +6.8%) FDA DMF, OSHA, TSCA, ISO 9001
European Union Oncology Intermediates, Fine Fine Chemicals, Agrochemicals Steady Demand (CAGR +5.2%) EU-REACH Registration, cGMP Annex 1
Asia-Pacific Contract Development & Manufacturing (CDMO), API Exports Rapid Expansion (CAGR +8.4%) NMPA Standards, PMDA Validation
Latin America / Africa Formulation Setup, Downstream Fine Chemical Processing Emerging Growth (CAGR +5.9%) Local MOH Licensing, COA Verification

China Factory Efficiency Advantages & Scale Economics

China's dominance in exporting 4-oxo-piperidine-1-carboxylic acid ethyl ester stems from an integrated supply chain that links basic petrochemical feeds directly to fine chemical intermediates. Facilities with an overall construction footprint exceeding 250,000 square meters utilize automated continuous flow reactors, micro-channel setups, and packed distillation columns.

This industrial setup offers distinct commercial benefits to international buyers:

  • Raw Material Security: Direct sourcing of piperidone precursors minimizes supply chain bottlenecks and protects against price volatility.
  • Green Chemistry Metrics: Implementation of Zero Liquid Discharge (ZLD) systems and low-energy solvent recovery lines ensuring compliance with global environmental standards.
  • Scalable Production Lines: Capabilities ranging from multi-kilogram custom pilot batches to multi-ton industrial scale production runs.
  • Analytical Excellence: End-to-end quality control utilizing high-performance liquid chromatography (HPLC) with charged aerosol detection (CAD), gas chromatography with flame ionization detection (GC-FID), and mass spectrometry.

Downstream Application Scenarios & Chemical Transformations

4-Oxo-piperidine-1-carboxylic acid ethyl ester serves as a essential precursor in multiple catalytic pathways:

Reductive Amination
Reacts with primary and secondary amines to form substituted 4-aminopiperidines—core pharmacophores found in neuro-receptor ligands and analgesics.
Horner-Wadsworth-Emmons
Olefination at the 4-keto site allows insertion of functionalized alkylidene chains, enabling synthesis of specialized spirocyclic structures.
Heterocycle Annulation
Acts as a 1,3-bifunctional precursor for bicyclic systems such as azaindoles and pyrazolopiperidines used in kinase inhibitor chemistry.
