Copper (II) acetate monohydrate 99% or Cupric acetate monohydrate or Copper diacetate monohydrate

Product Overview & Quality

Product Name: Copper (II) acetate monohydrate 99% or Cupric acetate monohydrate or Copper diacetate monohydrate
Brand: QReC (Product Code: QR-C5044-1-0500)
Grade: Analytical Reagent (AR Grade) featuring a certified chemical assay of not less than 99 percent. Manufactured and refined under strict QReC global laboratory standards. Rigorously regulated to maintain exceptionally low ppm thresholds of chloride, sulfate, water-insoluble matter, total nitrogen, and trace foreign heavy metals (such as iron, lead, nickel, zinc, and calcium). Dry, uniform crystal profile dissolves cleanly in water and dilute acids without leaving insoluble basic salts, ensuring high analytical reproducibility in biochemical and organic workflows. Packaged in a heavy-duty, chemically resistant container with a tight hermetic seal for light and atmospheric moisture protection.
Physical Properties: Dark bluish-green crystalline solid or fine blue-green powder. Faint, characteristic acetic acid odor. Stable under ordinary storage conditions; non-combustible alone, but thermal decomposition releases toxic copper fumes and irritating acetic acid vapors.
Solubility: Moderately soluble in water (approximately 7 grams per 100 milliliters at room temperature; solubility increases significantly in hot water); soluble in ethanol, methanol, and glycerol; freely soluble in aqueous ammonia solutions.
Key Use: Heavily utilized as the definitive primary reagent in formulating Barfoed reagent (combined with dilute acetic acid) for biochemical diagnostic screening to differentiate reducing monosaccharides (such as glucose and fructose) from reducing disaccharides (such as maltose and lactose), where monosaccharides rapidly reduce copper ions to yield a red cuprous oxide precipitate within 1 to 2 minutes. Extensively applied as an effective catalyst in organic synthesis, notably in oxidative carbon-carbon and carbon-nitrogen coupling reactions (such as Glaser alkyne coupling) and mild catalytic oxidation. Serves as a copper precursor for synthesizing advanced coordination complexes, metal-organic frameworks (MOFs), and copper oxide nanoparticles in material science. Routinely employed as a histological mordant in specialized biological staining techniques.

Safety & Hazards (Harmful, Serious Eye Damage & Aquatic Toxic)

Classification: Harmful if swallowed. Causes skin irritation. Causes serious eye damage. May cause respiratory irritation. Very toxic to aquatic life with long lasting effects.
Health Risks: Direct eye contact triggers instantaneous, severe caustic ulceration of the conjunctiva and cornea, accompanied by intense pain, corneal opacification, and permanent vision impairment. Prolonged dermal contact induces erythema, localized dermatitis, and contact sensitization. Inhalation of particulate dust severely irritates mucous membranes of the respiratory tract, causing sneezing, coughing, chest tightness, and potential metal fume fever symptoms. Ingestion produces severe gastrointestinal toxicity with a metallic taste, intense abdominal pain, nausea, characteristic blue-green vomiting, gastrointestinal bleeding, hemolysis, and potentially fatal acute hepatic and renal tubular necrosis.
First Aid Measures: Immediately flush affected eyes or skin with an abundant stream of clean running water for at least 15 to 20 minutes while stripping contaminated clothing. In case of dust inhalation, rapidly transfer the victim to fresh air. If accidentally swallowed, do NOT induce vomiting; thoroughly rinse mouth, administer water or milk immediately, and seek immediate, urgent emergency medical attention, alerting clinical staff to inorganic copper poisoning.

Handling & Storage

Storage: Toxic Heavy Metal Salt and Environmental Pollutant. Must be preserved in its original, tightly closed QReC container placed on secondary containment trays. Store in a cool, dry, and well-ventilated dedicated chemical store at stable room temperature (below 30 degrees Celsius), sheltered from direct sunlight and excessive humidity. Keep strictly segregated from strong oxidizing agents, strong mineral acids, strong bases, and active metals.
Precautions: Standard laboratory PPE is mandatory, including chemical-resistant nitrile gloves, splash-proof safety goggles, and a protective lab coat. Weigh and dispense carefully to prevent airborne dust generation. Never discharge copper-containing solutions or waste residues directly into municipal drains; collect exclusively in dedicated heavy-metal hazardous waste containers for certified environmental treatment.
