Introduction

C₄H₄O₄, also known as trans-butenedioic acid, is a stable dicarboxylic acid with consistent acidity and low hygroscopicity. It is widely used where controlled acidification and long-term stability are required.

Key Features

Strong Acid Strength
High acidity allows achieving target pH with less material, reducing usage.

Slow Dissolution Rate
Dissolves gradually, keeping pH stable; fully soluble within 30–60 minutes.

Good Storage Stability
Maintains color and odor under normal warehouse conditions over time.

Low Moisture Content
Moisture below 0.5% reduces clumping and improves powder flow.

Customization Services

Controlled Particle Size
Adjustable particle size to match mixing, dissolution, or processing requirements.

Moisture Adjustment
Moisture levels can be controlled to reduce clumping and maintain powder flow.

Purity Specification
Ability to meet specific purity ranges according to customer technical requirements.

Custom Supply Plans
