Octreotide Acetate
1. Basic Product Information
Product Name: Octreotide Acetate
CAS Number: 83150-76-9
Molecular Formula: C49H66N10O10S2·2C2H4O2
Molecular Weight: 1139.35
Chemical Name: L-Cysteinamide, D-phenylalanyl-L-cysteinyl-L-phenylalanyl-D-tryptophyl-L-lysyl-L-threonyl-N-[2-hydroxy-1-(hydroxymethyl)propyl]-, cyclic (2-7)-disulfide, acetate salt
Product Category: Synthetic Peptide API, Somatostatin Analog, Pharmaceutical Peptide Raw Material, Biochemical Research Reagent
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White to off-white lyophilized crystalline powder
- Odor: Odorless
- Solubility: Freely soluble in water, dilute acetic acid; soluble in methanol; slightly soluble in ethanol; insoluble in acetone, chloroform, petroleum ether
- Melting Point: 167–174 °C
- Optical Rotation: -15° ~ -10° (c=0.5, H?O)
- Hygroscopicity: Highly hygroscopic, sensitive to moisture in air
- Aqueous Stability: Stable under weak acidic conditions; hydrolyzes rapidly under alkaline or high-temperature environment
Chemical Characteristics
- Molecular Structure: Cyclic octapeptide with disulfide bond, two acetate counterions, multiple amino, hydroxyl and amide functional groups
- Pharmacological Mechanism: Synthetic long-acting somatostatin analog, potent inhibitor of growth hormone, insulin, glucagon and gastrointestinal hormone secretion
- Hydrolysis Risk: Disulfide bond and peptide bonds break under high temperature, strong alkali or long-term exposure to moisture, leading to loss of biological activity
- Photostability: Light-sensitive; UV irradiation triggers peptide degradation and discoloration
- Thermal Stability: Stable below 40 °C; irreversible decomposition above 80 °C
- Chemical Compatibility: Compatible with weak acidic aqueous buffers; incompatible with alkaline substances, strong oxidants, heavy metal ions
3. Main Application Fields
- Core Application: Human Pharmaceutical API
Approved therapeutic raw material for injection formulations; indicated for acromegaly, carcinoid tumor flushing and severe diarrhea, VIPoma watery diarrhea, acute variceal hemorrhage - Peptide Drug Intermediate
Key raw material for sustained-release microsphere depot formulations for long-acting monthly injection - Biomedical Laboratory Research Reagent
Standard somatostatin analog for endocrine, tumor cell proliferation and gastrointestinal pharmacology research - HPLC Reference Standard
Certified reference substance for related substance testing of octreotide acetate bulk drugs and injections
4. Platform Category & Product Group Selection Guide
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Pharmaceutical Intermediates
Reason: It is a prescription human pharmaceutical peptide API, classified under pharmaceutical intermediates; not veterinary or water treatment chemical categories.
2) English Product Group Dropdown Options
Recommended Selection: Pharmaceutical Chemicals
Do NOT select Basic Organic Chemicals; this product is regulated human pharmaceutical raw material, which matches the pharmaceutical chemical grouping.
3. Standard Foreign Trade Packaging Specification
5mg/10mg/50mg glass vial for lab research samples; 1g/5g aluminum foil vacuum bag, 25kg fiber drum lined with double PE inner bags for bulk API orders; customized sterile packaging available for pharmaceutical production
