Ufiprazole
1. Basic Product Information
Product Name: Ufiprazole
CAS Number: 73590-85-9
Molecular Formula: C17H19N3O2S
Molecular Weight: 329.42
Synonyms: Omeprazole sulfide, 5-Methoxy-2-[[(3,5-dimethyl-4-methoxy-2-pyridinyl)methyl]thio]-1H-benzimidazole
Product Category: Pharmaceutical Intermediate, Benzimidazole Derivative, Precursor of Proton Pump Inhibitor APIs
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White to off-white crystalline solid
- Odor: Odorless
- Solubility: Slightly soluble in DMSO, methanol and ethanol; insoluble in water and aliphatic hydrocarbons
- Melting Point: 122–126 °C
- Predicted Boiling Point: 539.7±60.0 °C
- Density (20 °C): 1.28±0.1 g/cm3
- Hygroscopicity: Non-hygroscopic under fully sealed dry storage
- Aqueous Stability: Stable under alkaline environment (pH 10.4–11.0); decomposes rapidly below pH 7.8
Chemical Characteristics
- Molecular Structure: Benzimidazole parent ring connected with pyridylmethyl sulfide side chain, contains methoxy, thioether and imidazole functional groups
- Core Synthetic Function: Key intermediate for oxidation synthesis of Omeprazole and Esomeprazole (gastric proton pump inhibitor APIs)
- Oxidation Reactivity: Sulfide group can be selectively oxidized to sulfoxide to form finished PPI drug molecules
- Photostability: Light-sensitive; long-term UV exposure triggers slow molecular degradation and discoloration
- Thermal Stability: Stable at room temperature; decomposition occurs above 130 °C, releasing irritating nitrogen-containing organic volatile fumes
- Chemical Compatibility: Compatible with anhydrous polar aprotic solvents; incompatible with acidic aqueous solutions, strong oxidants
3. Main Application Fields
- Core Application: Pharmaceutical Synthetic Intermediate
Exclusive raw material for manufacturing Omeprazole and Esomeprazole APIs, widely used in global anti-gastric acid drug production lines - Biochemical Research Reference Standard
Reference compound for metabolism research of proton pump inhibitors, used for HPLC impurity testing of Omeprazole bulk drugs - Laboratory Organic Synthesis Substrate
Model benzimidazole sulfide compound for sulfur oxidation and heterocyclic derivatization research
4. Platform Category & Product Group Selection Guide
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Pharmaceutical Intermediates
Reason: It is a core intermediate for human gastric disease APIs, classified as pharmaceutical intermediate, not veterinary or water treatment chemical.
2) English Product Group Dropdown Options
Recommended Selection: Pharmaceutical Chemicals
Do NOT select Basic Organic Chemicals; this product is a regulated human pharmaceutical intermediate, matching pharmaceutical chemical grouping.
3. Standard Foreign Trade Packaging Specification
1kg aluminum foil vacuum bag for lab samples; 25kg fiber drum lined with double PE inner bags for bulk industrial orders; customized packaging specifications are available upon request
