Product Introduction

Ammonium Acetate (CH₃COONH₄) is an odorless white crystalline solid with high water solubility and volatility characteristics. Produced via the controlled neutralization of glacial acetic acid with anhydrous ammonia in dedicated stainless steel reactors, our material is crystallized and dried under monitored thermal thresholds to control moisture absorption.
As a direct manufacturer, we operate continuous crystallization lines yielding stable, free-flowing crystal structures. Our production facility utilizes automated bagging systems under nitrogen blankets to prevent caking, ensuring chemical integrity from our reaction vessel to your receiving dock. Fully compliant with EU REACH pre-registration and registration frameworks, our supply chain ensures seamless cross-border regulatory clearance for European and global markets.

Applications

Pharmaceutical Synthesis: Functions as an intermediate and catalyst in active pharmaceutical ingredient (API) manufacturing, specifically in heterocyclic ring formations.

Analytical Chemistry & HPLC: Utilized as a volatile buffer salt in High-Performance Liquid Chromatography (HPLC) mobile phases and mass spectrometry (LC-MS) due to clean evaporation without salt residue.

Biochemical Reagents: Applied in protein precipitation, gel electrophoresis buffer preparation, and cell culture media formulation.

Industrial Processing: Used in textile dyeing auxiliaries, biodegradable foam production, and specific rubber vulcanization processes.

Product Grades & Options

ACS / Reagent Grade: Designed for analytical laboratories, HPLC mobile phase preparation, and trace-sensitive chemical synthesis. Meets American Chemical Society specifications.

Pharma Intermediate Grade: Tailored for API synthesis, produced under strict impurity-profile monitoring to ensure low heavy metal, chloride, and sulfate limits.

Industrial Grade: Optimized for textile processing, catalysts, and bulk chemical applications where cost-efficiency is balanced with consistent purity (≥ 98.0%).

Custom particle size distribution and tailored moisture limits are available upon technical evaluation.

Quality Control & Documentation

Our quality assurance protocols govern every production batch prior to release:

In-Process Monitoring: Real-time titration and temperature logging during neutralization prevent unreacted acid or excess ammonia.

Instrumental Testing: Every batch is verified using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for heavy metal tracking and Karl Fischer titration for moisture control.

Traceability & Retention: Retained samples are kept for 24 months from the manufacturing date. Each lot is linked to raw material source records and reactor logs, maintained for five years.

Documentation Provided: A batch-specific Certificate of Analysis (COA), Safety Data Sheet (SDS), ISO 9001 compliance verification, and REACH compliance data accompany shipments upon request.

Packaging & Storage

Standard Packaging:

25 kg polyethylene-lined inner kraft paper bags.

25 kg fiber drums with double moisture barrier liners.

Bulk super sacks (500 kg / 1000 kg) fitted with PE inner liners for industrial users.

Storage Conditions: Store in a cool, dry, well-ventilated area away from strong oxidizing agents and acids. Keep containers tightly sealed to prevent moisture absorption and caking, as the product is hygroscopic.

Shelf Life: 24 months when stored under recommended conditions.

FAQ

Q: What is the primary method used to prevent caking during storage?

A: Our production process utilizes controlled vacuum drying to keep residual moisture below 0.5%. Combined with multi-layer moisture-barrier packaging (PE liners and sealed drums), this prevents moisture uptake and subsequent caking.

Q: Is this product suitable for LC-MS applications?

A: Yes. Our ACS/Reagent grade Ammonium Acetate has low residue after ignition (≤ 0.01%) and minimal UV-absorbing impurities, making it compatible with LC-MS volatile mobile phase requirements.

Q: Can you provide batch-specific heavy metal test results prior to shipment?

A: Yes. Every shipment includes a Certificate of Analysis detailing actual ICP-MS test figures for lead, iron, and other trace heavy metals.

Q: Is the product fully compliant with EU REACH regulations?

A: Yes. Our Ammonium Acetate is fully REACH registered for export and distribution within the European Union, ensuring zero customs compliance friction.

Q: What is the standard minimum order quantity (MOQ) for custom particle sizes?

A: The standard MOQ for custom milling or specialized particle size distribution is 1,000 kg per production run.

Q: What are the primary shipping hazards associated with this material?

A: Ammonium Acetate is classified as a non-hazardous chemical for standard ocean and land transportation, requiring no specialized hazardous material surcharges.
