Anisic Acid
1. Basic Product Information
Product Name: Anisic Acid
CAS Number: 100-09-4
Molecular Formula: C8H8O3
Molecular Weight: 152.15
Synonyms: p-Anisic acid, 4-Methoxybenzoic acid
Product Category: Cosmetic preservative, food flavor intermediate, pharmaceutical synthetic intermediate, aromatic carboxylic acid fine chemical
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White crystalline powder
- Odor: Faint mild aromatic odor
- Solubility: Soluble in ethanol, methanol, ether, chloroform; slightly soluble in hot water; insoluble in cold water and aliphatic hydrocarbons
- Melting Point: 183–186 °C
- Density (20 °C): 1.28 g/cm3
- Hygroscopicity: Non-hygroscopic under sealed dry storage
- Aqueous Stability: Stable under neutral and weakly acidic aqueous systems; forms corresponding salts under alkaline conditions without rapid room-temperature degradation
Chemical Characteristics
- Molecular Structure: Para-methoxy substituted benzoic acid, aromatic carboxylic acid with methoxy functional group
- Core Functional Mechanism: Mild broad-spectrum antibacterial preservative active against gram-positive bacteria; used for esterification, salt formation and cyclization reactions to synthesize flavors, UV absorbers and drug intermediates
- Photostability: Moderately light-sensitive; long-term UV exposure generates slight yellow impurities
- Thermal Stability: Stable below 150 °C; heating above melting point causes decarboxylation decomposition
- Chemical Compatibility: Compatible with cosmetic surfactants, alcohols and neutral pharmaceutical excipients; incompatible with strong oxidants, concentrated strong alkalis and heavy metal ions
3. Main Application Fields
- Core Application: Cosmetic Preservative Raw Material
Antiseptic additive for skincare, hair care and body care formulations to inhibit bacterial reproduction, replace partial parabens - Food Flavor & Fragrance Intermediate
Starting material for manufacturing anisate ester flavors with sweet anise aroma - Pharmaceutical Synthetic Intermediate
Raw material for synthesis of anti-inflammatory, analgesic and anti-tumor drug intermediates - Dye & UV Absorber Precursor
Synthetic raw material for benzophenone series UV absorbers and aromatic organic dyes - Laboratory Chromatography Standard
Carboxylic acid reference standard for HPLC organic acid detection
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Cosmetic Additives
Reason: Methoxybenzoic acid widely used as daily chemical preservative and fine chemical synthetic raw material
2) English Product Group Dropdown Options
Recommended Selection: Basic Organic Chemicals
Do NOT solely classify as pharmaceutical chemicals; it is universal cosmetic and flavor industrial intermediate
3. Standard Foreign Trade Packaging Specification
1kg nitrogen-sealed aluminum foil vacuum bag for lab synthesis tests; 25kg double PE-lined lightproof fiber drum for bulk cosmetic grade batches
