(+)-Cloprostenol sodium
1. Basic Information
Name: (+)-Cloprostenol sodium
Alias: Cloprostenol sodium salt, (9S,11R,15S)-16-(3-chlorophenoxy)-9,11,15-trihydroxy-17,18,19,20-tetranorprosta-4,5,13-trien-1-oic acid sodium
CAS No.: 62561-03-9
Molecular Formula: C22H28ClNaO6
Molecular Weight: 446.90
Category: Synthetic prostaglandin veterinary API, animal reproductive regulation drug raw material, prostaglandin heterocyclic chiral intermediate
2. Physical and Chemical Properties
Physical Properties
- Appearance: White to off-white amorphous lyophilized crystalline powder
- Odor: Odorless, slight bitter taste
- Solubility: Freely soluble in water, methanol, ethanol; slightly soluble in acetone; insoluble in ethyl acetate, petroleum ether, alkanes
- Melting Point: Decomposes above 165 ℃
- Specific Rotation [α]???: +22° ~ +28° (c=1, methanol)
- Density (predicted): 1.29 g/cm3
- Hygroscopy: Strongly hygroscopic under high humidity
- Aqueous property: Weakly alkaline aqueous solution, stable within pH 6–9
Chemical Properties
- Molecular structure: Chiral prostaglandin sodium salt, contains chlorophenoxy side chain, three hydroxyl groups, conjugated triene carboxylic acid sodium salt, multiple chiral carbon centers with stable (+) optical configuration
- Salt dissociation: Dissociates into cloprostenol anion and sodium ion after dissolving in water, improves water solubility for injection preparation
- Double bond oxidation: Conjugated triene structure easily oxidized by air and UV light, leading to reduced biological activity and discoloration
- Hydroxyl reactivity: Polyhydroxy groups can form ester derivatives under acid catalysis; carboxylic acid group undergoes esterification, amidation
- Thermal stability: Stable below 60 ℃; high temperature heating triggers double bond polymerization and decomposition, loss of estrus regulation activity
- Photostability: Extremely light-sensitive, long-term light storage turns pale yellow-brown
- Compatibility: Compatible with neutral aqueous buffer, low-carbon alcohols; incompatible with strong oxidants, concentrated strong acid, heavy metal ions

Safety Warning
Irritant chlorinated prostaglandin powder. Dust irritates eyes, nasal tract and respiratory tract; skin contact may cause local vasodilation, redness and itching; pregnant operators must avoid exposure, may induce uterine contraction risk. All operations must be carried out in sterile ventilated fume hood with dust-proof respirator, splash-proof goggles and chemical-resistant nitrile gloves. Strictly avoid contact with strong oxidants to prevent conjugated double bond oxidation and activity loss. Waste liquid neutralized before discharge; solid waste classified as veterinary hormone hazardous waste disposed by licensed professional institutions.
