Product Introduction

Magnesium Succinate (C₄H₄MgO₄) is an organic magnesium salt synthesized through precision neutralization of high-purity succinic acid and magnesium sources, followed by controlled crystallization. It functions as a bioavailable magnesium source in nutritional formulations and a specialized reaction intermediate in chemical synthesis.

Our production plant operates under strict ISO 9001 quality management frameworks, utilizing dedicated clean-reaction systems to maintain lot-to-lot traceability and chemical purity for regulated industrial sectors.

CAS Number: 556-32-1 (Anhydrous and Hydrate variants available)

Applications

Nutritional & Dietary Supplements: Utilized as an organic magnesium carrier in capsules, tablets, and functional beverage premixes, selected for digestive compatibility.

Pharmaceutical Synthesis: Acts as a specialized chemical intermediate in organic synthesis pathways and active ingredient processing.

Polymer & Chemical Additives: Employed as a stabilizer and modifying agent in specialized high-performance polymer formulations.

Product Grades & Processing Options

To accommodate different formulation requirements, we offer customized physical processing:

Particle Size Distribution (PSD)

Standard Grade: D90 < 100 μm (optimized for general blending).

Micro-Milled Grade: D90 < 45 μm (engineered via jet-milling for enhanced suspension stability and rapid dissolution).

Moisture Formats: Available in both hydrated forms and strictly dried low-moisture variants for moisture-sensitive formulations.

Quality Control & Manufacturing Evidence

Facility Standards: Our facility integrates automated dosing, closed-loop crystallization, and HEPA-filtered drying environments to minimize airborne contamination.

Batch Testing Protocol: Every production lot is tested internally using ICP-MS, HPLC, and laser diffraction particle analyzers before issuance of the Certificate of Analysis (COA).

Regulatory Support: Full documentation packages available, including animal-origin-free (AOF) statements, GMO-free certificates, and heavy metal compliance data.

Packaging & Storage

Standard Packaging

25 kg fiber drums equipped with dual low-density polyethylene (LDPE) heat-sealed inner liners.

Moisture-barrier aluminum foil laminate bags available for hygroscopic custom grades.

Storage Guidelines: Store in tightly sealed containers in a dry, cool, well-ventilated warehouse. Keep away from strong oxidizing materials.

Shelf Life: 24 months from the date of manufacture when stored under recommended conditions.

FAQ

Q: What is the primary functional difference between anhydrous and hydrated Magnesium Succinate?

A: Hydrated versions incorporate bound crystal water molecules, which lowers the relative elemental magnesium percentage per unit weight. Anhydrous grades provide a higher active magnesium concentration per gram and are selected when water introduction must be strictly avoided in dry-powder blends.

Q: Can particle size distribution be customized for our manufacturing process?

A: Yes. Using industrial air-jet milling equipment, we can adjust the particle size distribution (D90) to match your specific powder flowability, compression, or suspension dissolution criteria.

Q: What quality documents accompany commercial deliveries?

A: Each shipment includes a lot-specific Certificate of Analysis (COA) detailing exact assay values, heavy metal limits, loss on drying, and pH. Safety Data Sheets (SDS) and regulatory statements are provided digitally upon order confirmation.

Q: What is the standard Minimum Order Quantity (MOQ) for commercial orders?

A: The standard commercial MOQ is 500 kg (custom bulk terms negotiable). However, 1 kg to 5 kg sample quantities can be provided for laboratory scale-up, R&D evaluation, and analytical testing.

Q: How do you control batch-to-batch chemical consistency?

A: Consistency is maintained by locking raw material supplier channels, controlling reactor thermodynamics (temperature gradients and agitation rates), and adhering to strict internal QC release criteria across every single batch.

Q: Are on-site customer quality audits permitted?

A: Yes. We routinely host quality assurance and technical audit teams from pharmaceutical and industrial procurement partners at our manufacturing site, subject to standard scheduling and non-disclosure agreements.
