Appearance: colorless powder CAS: 150-83-4 Product ID: HOBU13 Purity: 99%+ Formula: C4H8NaO3 MW: 127.09g/mol MP: 167-170 °C Solubility: water soluble HS Code: 291819 MDL: MFCD00016716 SMILES: [Na].O=C(O)CC(O)C Sodium 3-hydroxybutyrate is an is an energy-dense, chiral, bio-derived C4 carboxylate used as a ketosis signaling molecule in proteomics studies. Structurally, sodium 3-hydroxybutyrate contains a butyrate core with a single hydroxyl substituent in position 3. The 3-Hydroxybutyrate moiety, also known as beta-hydroxybutyric acid (BHB), and ketone body, is a natural metabolite formed during fatty acid digestion during periods of prolonged exercise, starvation, or absence of dietary carbohydrates. As a chiral molecule, it is also used in the pharmaceutical and chemical industries as a building block for the synthesis of important chiral compounds.
