(S)-Equol is a bioactive isoflavan compound associated with the metabolism of daidzein, a soy isoflavone. It has attracted interest in nutritional science, dietary ingredient development, and biochemical research due to its distinct chemical structure and biological activity.
Unlike racemic equol, (S)-Equol represents a specific stereoisomer. This distinction is important for manufacturers and ingredient buyers who require a defined molecular form for product development, research, or specialized formulation.
Khonor supplies specialty chemical raw materials and functional ingredients to international B2B customers. We support sourcing inquiries for (S)-Equol, including product specifications, quality documentation, packaging, and export requirements.

(S)-Equol is of interest to nutritional ingredient developers and supplement manufacturers working with isoflavans and other specialized bioactive compounds. Its suitability for a finished dietary supplement depends on product quality, intended use, and the regulatory requirements of the target market.
(S)-Equol is used in biochemical research investigating isoflavans, estrogen receptor interactions, and related biological pathways. Its defined stereochemistry makes it relevant to studies requiring a specific equol isomer.
Manufacturers developing specialized formulations may source (S)-Equol as a defined chemical ingredient. Purity, stereochemical identity, impurity profile, and analytical documentation are important considerations when selecting a suitable raw material.
Defined Stereoisomer: Specifically identified as (S)-Equol rather than a racemic equol mixture.
Established Chemical Identity: CAS number 531-95-3 and molecular formula C₁₅H₁₄O₃.
Specialty Ingredient: Relevant to nutritional ingredient development and biochemical research.
Quality-Focused Sourcing: Identity, purity, and supporting analytical documentation are important purchasing criteria.
Packaging: Packaging requirements can be discussed according to the product grade and order quantity.
Storage: Follow the storage conditions specified in the product's technical documentation and label. Protect the material from unsuitable environmental conditions and keep the container properly sealed.
Q1: What is the CAS number of (S)-Equol?
The CAS number of (S)-Equol is 531-95-3.
Q2: What is the molecular formula of (S)-Equol?
Its molecular formula is C₁₅H₁₄O₃, and its molecular weight is 242.27 g/mol.
Q3: What is the difference between (S)-Equol and racemic equol?
(S)-Equol is one specific stereoisomer, whereas racemic equol contains both S and R enantiomers. Buyers should confirm stereochemical identity when this distinction matters for their application.
Q4: What should buyers check when sourcing (S)-Equol?
Key considerations include assay, stereochemical identity, impurity profile, analytical methods, and batch-specific quality documentation.
