Boldenone Undecylenate
1. Basic Product Information
Product Name: Boldenone Undecylenate
CAS Number: 13103-34-9
Molecular Formula: C30H44O3
Molecular Weight: 452.67
Synonyms: 1-Dehydrotestosterone undecylenate, Boldenone 17-undecenoate
Product Category: Veterinary anabolic steroid raw material, hormone research biochemical reagent, controlled steroid intermediate
2. Physical and Chemical Properties
Physical Indicators
- Appearance: Pale yellow to light yellow oily viscous liquid
- Odor: Faint characteristic ester odor
- Solubility: Soluble in sesame oil, benzyl benzoate, ethanol, chloroform, ethyl acetate; insoluble in water
- Boiling Point: Decomposes at high temperature without fixed boiling point
- Density (20 °C): 1.03–1.06 g/cm3
- Refractive Index: 1.485–1.492
- Flash Point: >110 °C
- Hygroscopicity: Non-hygroscopic under sealed dry storage
- Aqueous Stability: Stable in neutral and weak oily systems; ester hydrolysis occurs under high temperature, strong alkaline aqueous environment to generate free boldenone
Chemical Characteristics
- Molecular Structure: Polycyclic steroid parent ring with double bond at C1 position, 17β-undecylenate long-chain ester group
- Core Functional Mechanism: Long-acting anabolic androgenic steroid; significantly boosts protein synthesis, promotes livestock muscle growth and fat reduction; strictly prohibited for human body injection or oral use
- Photostability: Strongly light-sensitive; UV exposure leads to deep yellow discoloration and activity attenuation
- Thermal Stability: Stable below 80 °C; prolonged heating above 100 °C accelerates ester hydrolysis
- Chemical Compatibility: Compatible with oily injection solvents; incompatible with strong alkalis, strong oxidants and heavy metal ions
3. Main Application Fields
- Core Application: Veterinary Growth-Promoting Steroid API
Raw material for long-acting oil injection preparations for cattle, used to improve meat yield; strictly regulated and restricted by veterinary drug supervision authorities globally - Biochemical Research Reagent
Androgen receptor agonist standard for endocrinology, muscle cell metabolism and steroid pathway laboratory research - Steroid Synthetic Intermediate
Long-chain ester steroid substrate for synthesis of other modified anabolic steroid derivatives
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Veterinary Drug Intermediates
Reason: Regulated long-acting veterinary anabolic steroid ester intermediate
2) English Product Group Dropdown Options
Recommended Selection: Basic Organic Chemicals
Do NOT select Pharmaceutical Chemicals for human drugs; it is animal-use controlled hormone raw material
3. Standard Foreign Trade Packaging Specification
100mL nitrogen-sealed amber glass bottle for lab reference samples; 1L sealed PE-lined light-proof metal can for pilot batches; customs supervised sealed packaging required for cross-border bulk shipment
