Product Overview
4-tert-Butylbenzoic acid is an aromatic carboxylic acid intermediate selected for downstream formulations and synthesis routes, including lubricant and cutting-fluid additive value chains. Buyers normally compare assay, acid value, colour and trace-metal limits because these affect downstream consistency.
Available Grades and Forms
- Existing record lists ≥99% assay; confirm current grade
Key Functions
- Acts as a synthesis intermediate for functional derivatives
- Provides a defined aromatic carboxylic-acid building block
- Supports lubricant-additive and alkyd-modifier production routes
Typical Applications
- Synthesis of downstream functional derivatives for lubricant-additive packages
- Production of modifiers used in selected coating-binder value chains
- Specialty organic synthesis routes that specify PTBBA as a starting material
Selection Considerations
- Assay and acid value
- Melting range
- Colour requirement
- Moisture, ash and iron limits
- Downstream reaction and filtration requirements

Quality and Documentation
COA, TDS, SDS, batch information, export documents and packing information can be coordinated for the offered product when available. No certificate is implied until confirmed in writing.
Supply Model
Global Supply Product. Direct manufacturing and authorised distribution have not been verified.
Bulk Supply and Export
For PTBBA, submit the complete analytical limits rather than purity alone. Batch documentation, packing and shipment planning can then be aligned with the downstream synthesis schedule.
