Ectoine Chemicals Introduction
Chemical Properties
- Chemical Name: (S)-2-Methyl-1,4,5,6-tetrahydropyrimidine-4-carboxylic acid
- CAS Number: 96702-03-3
- Molecular Formula: C₆H₁₀N₂O₂
- Molecular Weight: 142.16 g/mol
- Appearance: White to off-white crystalline powder
- Solubility: Highly soluble in water, ethanol, and glycerol; slightly soluble in propylene glycol
- Melting Point: ~280°C (decomposition)
Applications
- Agriculture:
- Enhances plant stress resistance against drought, salinity, and extreme temperatures by stabilizing cell membranes and osmotic balance.
- Promotes root development and nutrient uptake, improving crop yields (e.g., corn, rapeseed).
- Cosmetics:
- Forms a protective water shell around skin cells for intense hydration.
- Repairs UV-induced DNA damage, reduces inflammation, and suits sensitive/damaged skin.
- Pharmaceuticals:
- Stabilizes proteins and peptides in drug formulations.
- Investigated for neuroprotective effects in neurological disorders.
Mechanism of Action
- Osmolyte Function: Binds 4–5 water molecules per molecule, maintaining cellular hydration under stress.
- Anti-Inflammatory: Suppresses pro-inflammatory cytokines (e.g., TNF-α), modulating immune responses.
Safety & Production
- Toxicity: Generally recognized as safe (GRAS); non-irritating at recommended concentrations. Oral LD₅₀ in rats >5,000 mg/kg.
- Synthesis: Produced via microbial fermentation using Halomonas strains, followed by crystallization.
