Sodium oxalate or Disodium oxalate

Product Overview & Quality

• Product Name: Sodium oxalate or Disodium oxalate
• Brand: QReC (Product Code: QR-D3248-1-0500)
• Grade: Analytical Reagent (AR Grade) featuring an exceptional premium chemical purity of 99.8 percent or higher. Manufactured and rigorously quality-tested under QReC strict global laboratory standards to ensure trace-level thresholds of moisture, insoluble matter, chloride, sulfate, and heavy metals (such as iron and lead). Due to its remarkable stoichiometric stability, non-hygroscopic crystalline nature, and reproducibility, it serves as an authoritative primary standard reagent for high-precision quantitative analysis.
• Physical Properties: White crystalline solid or fine white crystalline powder. Odorless, non-volatile, and chemically stable under standard atmospheric temperatures.
• Solubility: Moderately soluble in ambient water (approximately 3.7 grams per 100 milliliters at room temperature; solubility increases significantly in boiling water); insoluble in ethanol and diethyl ether.
• Key Use: Heavily utilized as an authoritative primary reference standard for standardizing volumetric potassium permanganate (KMnO4) solutions in redox titration workflows. Extensively applied as a selective precipitating agent for the quantitative gravimetric and volumetric determination of calcium ions. Commonly employed as a specialized analytical reagent for buffer preparations, biochemical assays, and laboratory-scale anticoagulant testing systems.

Safety & Hazards (Critical & Toxic)

• Classification: Harmful if swallowed. Harmful in contact with skin. Causes serious eye irritation.
• Health Risks: Direct eye contact triggers immediate burning irritation, conjunctival redness, and profuse watering. Direct dermal exposure causes mechanical and chemical skin irritation. Inhalation of particulate dust irritates the mucous membranes of the nose and throat, causing coughing and respiratory discomfort. Ingestion presents systemic toxicity: oxalate ions precipitate systemic calcium, precipitating acute hypocalcemia, abdominal pain, severe nausea, vomiting, convulsions, and severe renal damage via insoluble calcium oxalate crystal deposition in the kidneys.
• First Aid Measures: Flush eyes or skin immediately with abundant flowing water for at least 15 minutes while removing contaminated garments. If dust is inhaled, move the victim to fresh air. If swallowed, rinse mouth thoroughly, give plenty of water to drink if conscious, and seek immediate emergency medical attention.

Handling & Storage

• Storage: Store in its original, tightly sealed QReC laboratory container. Keep in a cool, dry, and well-ventilated chemical storage zone at stable room temperature (below 30 degrees Celsius). Protect from direct sunlight and ambient humidity. Keep completely isolated from strong oxidizing agents and strong mineral acids.
• Precautions: Standard laboratory PPE is mandatory, including chemical-resistant gloves, safety goggles, a protective lab coat, and a particulate dust respirator mask during weighing. Ensure container caps are tightly replaced immediately after use.
