Technical Specifications of Ethyl (R)-(-)-4-cyano-3-hydroxybutyrate for R&D

For researchers and development scientists in the pharmaceutical and chemical industries, a thorough understanding of the technical specifications of key intermediates is crucial for successful project outcomes. Ethyl (R)-(-)-4-cyano-3-hydroxybutyrate (CAS: 141942-85-0) is one such critical compound, widely utilized as a chiral building block in complex organic synthesis, particularly for statin drugs. As a prominent manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of these specifications.

Key Physicochemical Properties

When you buy Ethyl (R)-(-)-4-cyano-3-hydroxybutyrate, these technical details are vital for its effective application:

  • Appearance: Typically a colorless to pale yellow viscous liquid. This visual characteristic is an initial indicator of product quality.
  • Purity (HPLC/GC): Guaranteed purity of 97%min, often exceeding 98% or 99% for critical applications, ensures minimal interference from impurities in synthesis.
  • Molecular Formula & Weight: C7H11NO3, with a molecular weight of 157.17 g/mol, providing essential data for stoichiometric calculations.
  • CAS Number: 141942-85-0 – the definitive identifier for this chemical entity.
  • Optical Rotation: The characteristic optical rotation, such as [α]D20 = -12.5° to -14.5° (c=1, MeOH), confirms the desired (R)-chirality.
  • Boiling Point: Approximately 285°C (with decomposition), indicating thermal stability under certain conditions.
  • Solubility: Miscible with common organic solvents like ethanol, acetone, and DMSO, but immiscible with water, guiding formulation and reaction solvent choices.
