4298-05-9 - Introduction
cis-3-hydroxy-dl-proline(cis-3-hydroxy-dl-proline) is an organic molecule containing a hydroxyl group and a proline structure. Its properties are as follows:
1. Appearance: The cis-3-hydroxy-dl-proline is white crystalline powder.
2. solubility: soluble in water and alcohol solvents, insoluble in organic solvents.
3. Stability: Stable at room temperature, but may decompose under high temperature and strong acid and alkali conditions.
cis-3-hydroxy-dl-proline have multiple uses:
1. Pharmaceutical field: cis-3-hydroxy-dl-proline is an important unnatural amino acid, which can be used as a precursor for the synthesis of antibiotics, bacteriostats and other biologically active compounds.
2. food additives: cis-3-hydroxy-dl-proline can be used as food preservative, with antibacterial and antioxidant effect.
3. cosmetics industry: cis-3-hydroxy-dl-proline can be used to add skin care products and make-up products, with moisturizing and anti-aging function.
The method of preparing cis-3-hydroxy-dl-proline includes obtaining by chemical synthesis or microbial fermentation. A common method of chemical synthesis is to react proline with an appropriate compound to form a hydroxyl group by selective addition or substitution. Microbial fermentation uses the metabolic processes of certain strains of microorganisms to produce cis-3-hydroxy-dl-proline.
Regarding safety information, the cis-3-hydroxy-dl-proline is relatively safe under general conditions of use. However, if used at high temperature, high pressure or under strong acid and alkali conditions, reactivity and toxicity risks may occur.
