1. Basic Information
Name: Dehydroepiandrosterone
Abbreviation: DHEA
Alias: 3β-Hydroxyandrost-5-en-17-one
CAS No.: 53-43-0
Molecular Formula: C19H28O2
Letter-number format molecular formula: C19H28O2
Molecular Weight: 288.43
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline powder
- Odor: Odorless
- Solubility: Insoluble in water; soluble in ethanol, methanol, chloroform, acetone, ether; slightly soluble in vegetable oil
- Melting Point: 148–153 °C
- Hygroscopicity: Non-hygroscopic under normal ambient humidity
- Crystal feature: Flaky crystal after recrystallization from ethanol
Chemical Properties
- Molecular Structure: Natural steroid hormone, four-ring androstane skeleton, containing hydroxyl group and ketone group, with C5-C6 carbon-carbon double bond
- Functional group reactivity: Secondary hydroxyl group can undergo esterification and oxidation; ketone group can generate oxime through condensation reaction
- Stereostability: Natural configuration is stable at room temperature; high temperature will cause partial double bond isomerization
- Thermal stability: Stable below 120 °C; obvious decomposition above 220 °C
- Photostability: Sensitive to strong UV light; long-term light exposure turns pale yellow and produces related impurities
- Compatibility: Compatible with neutral lipid excipients; incompatible with strong oxidants, concentrated strong acid and heavy metal ions
3. Main Application Fields
1. Pharmaceutical API & Steroid Intermediate (Core Application)
- Raw material for synthesizing estrogen, androgen, contraceptive steroid drugs
- Functional health raw material for regulating human endocrine and improving physical fatigue
2. Biochemical Research Reagent
Standard steroid reagent for cell culture, endocrinology animal model experiments; HPLC reference standard for hormone detection
3. Cosmetic Functional Additive
Anti-aging raw material added to high-end skincare products to regulate skin cell metabolism

Safety Warning
Hormonal active steroid substance. Dust inhalation irritates eyes and respiratory tract; long-term skin contact may interfere human endocrine balance. Pregnant women, minors are prohibited from direct contact. Wear dust mask, chemical-resistant gloves and safety goggles during operation. Avoid long-term high temperature and light exposure to prevent degradation impurity generation. Waste residues and waste liquid are pharmaceutical organic hazardous waste and need professional centralized disposal.
