Uses:

2,5-Dihydroxyterephthalic Acid (DHTA)

2,5-Dihydroxyterephthalic Acid (commonly abbreviated as DHTA, CAS No. 610-92-4) is an aromatic dicarboxylic acid with the molecular formula C₈H₆O₆ and a molecular weight of 198.13 g/mol. Its structure consists of a benzene ring bearing two hydroxyl (–OH) groups at positions 2 and 5, and two carboxylic acid (–COOH) groups at positions 1 and 4. This gives it a highly symmetrical, planar geometry stabilized by intramolecular hydrogen bonding.

Key Physical Properties

Property	Value
Appearance	Dark gray to green / light yellow solid
Melting Point	>300 °C
Boiling Point	~498.9 °C
Density	~1.779 g/cm³
Solubility	Soluble in hot dimethylformamide (DMF); poorly soluble in water and most organic solvents
pKa	~2.17

Applications & Selling Points

DHTA is a versatile, high-value organic intermediate with broad applications across multiple industries. Here are its major uses and the selling points that make it attractive:

1. Metal-Organic Frameworks (MOFs)

DHTA serves as a critical organic linker in constructing MOFs — highly porous crystalline materials. The dual hydroxyl and carboxyl groups enable strong coordination with metal ions (e.g., Cu, Fe, Co, Eu), forming frameworks with tunable pore sizes. These MOFs are used for:

Gas adsorption & storage (CO₂ capture, hydrogen storage)

Catalysis

Drug delivery systems

Luminescent sensing (e.g., Eu³⁺ complexes for fluorescence)

Selling point: The growing global demand for MOF-based technologies in clean energy and environmental remediation drives strong, sustained demand for high-purity DHTA.

2. High-Performance Fibers (PIPD / M5)

DHTA is an essential monomer for synthesizing PIPD (poly{2,6-diimidazo[4,5-b:4',5'-e]pyridinylene-1,4(2,5)-dihydroxyphenylene}), also known as M5 fiber — an ultra-high-strength, heat-resistant aromatic heterocyclic polymer fiber. It is produced by condensation with 2,3,5,6-tetraaminopyridine (TAP).

Selling point: PIPD/M5 fibers compete with Kevlar and carbon fiber in aerospace, military, and industrial applications. The quality and purity of DHTA directly determine the polymerization outcome and final fiber performance.

3. Pharmaceutical Intermediates

The four reactive functional groups (two –OH and two –COOH) make DHTA an exceptionally versatile building block for drug synthesis. It is used to develop:

Anticancer agents (via metal-coordination bioactive complexes)

Antibacterial compounds

Antioxidants

Drug delivery carriers (enhancing solubility, stability, or targeted release)

Selling point: As a multi-functional pharmaceutical intermediate, DHTA enables diverse chemical modifications, making it a high-value starting material for novel drug discovery pipelines.

4. Dyes, Pigments & Fluorescent Materials

DHTA is used in the synthesis of:

Azo dyes — its phenolic hydroxyl groups influence color shade, intensity, and fastness

Fluorescent materials — the aromatic system with electron-donating –OH groups contributes to fluorescence, useful in optical brighteners, biological imaging probes, and security inks

High-solubility organic light-emitting polymers

Selling point: The ability to tailor fluorescence and color properties makes DHTA a sought-after component for advanced optical and specialty dye applications.

5. Battery Materials (Emerging Market)

DHTA is increasingly recognized as an electrode material for:

Sodium-ion batteries

Aqueous zinc-ion batteries

It can function as both anode and cathode material, effectively improving conductivity and cycle life.

Selling point: This is a rapidly growing emerging demand segment. As the battery industry expands, DHTA's role in next-generation energy storage positions it for significant market growth.

6. Polyesters & Copolyethers

When blended with terephthalic acid, DHTA can react with ethylene glycol to produce linear polyesters or copolyethers with film-forming and fiber-forming properties.

Summary of Key Selling Points

Selling Point	Description
Multi-functional reactivity	Four reactive groups (2× –OH, 2× –COOH) enable diverse chemical modifications
High thermal stability	Melting point >300 °C makes it suitable for demanding processing conditions
MOF linker demand	Critical component in the booming MOF market for gas storage, catalysis, and sensing
High-performance fiber monomer	Essential for PIPD/M5 fiber — a next-gen material competing with Kevlar
Pharmaceutical versatility	Key intermediate for anticancer, antibacterial, and drug delivery research
Emerging battery applications	New growth driver in sodium-ion and zinc-ion battery electrode materials
Optical & dye applications	Enables fluorescent materials, specialty dyes, and light-emitting polymers

In short, DHTA is a niche but strategically important chemical whose value spans from traditional dye and polymer chemistry to cutting-edge applications in MOFs, high-performance fibers, pharmaceuticals, and next-generation batteries.
