563-72-4 Usage
Description
Calcium oxalate, also known as oxalate of lime, is a chemical compound that forms envelope-shaped crystals, commonly found in plants as raphides. It is a major constituent of human kidney stones and is also present in beerstone, a scale that forms on containers used in breweries. Its chemical formula is CaC2O4 or Ca(COO)2. Calcium oxalate is a white precipitate, insoluble in weak acids but soluble in strong acids, and is formed by the reaction of soluble calcium salt solution and ammonium oxalate solution.
Uses
Used in Ceramic Industry:
Calcium oxalate is used as a component in the manufacture of ceramic glazes for its unique properties and contribution to the final product's appearance and quality.
Used in Pharmaceutical Applications:
Calcium oxalate is used in the pharmaceutical industry due to its potential toxic effects when ingested, as seen in plants like dumb cane and rhubarb. It can cause sores, numbing, and even be fatal in high concentrations.
Used in Brewing Industry:
Calcium oxalate, known as 'beer stone,' is a brownish precipitate that tends to accumulate within vats, barrels, and other containers used in the brewing of beer. It is important to identify and manage its presence to maintain the quality of the beer.
Used in Medical Diagnostics:
The physical properties of calcium oxalate crystals, which often resemble a 6-sided prism, are used in medical diagnostics, particularly in the identification of kidney stones. More than 90% of the crystals in a urine sediment will have this type of morphology, making it crucial for quick identification in case of emergency.
Health Hazard
Even a small dose of calcium oxalate is enough to cause intense sensations of burning in the mouth and throat, swelling, and choking that could last for up to two weeks . In greater doses it can cause severe digestive upset, breathing difficulties, coma or even death. Recovery from severe oxalate poisoning is possible, but permanent liver and kidney damage may have occurred. The stalks of plants in the Dieffenbachia genus produce the most severe oxalate reactions. The needle - like oxalate crystals produce pain and swelling when they contact lips, tongue, oral mucosa, conjunctiva, or skin. Edema primarily is due to direct trauma from the needle-like crystals and, to a lesser extent, by other plant toxins (e.g., bradykinins, enzymes). Depending on the plant ingested, mild (Elephant Ear Colocasia esculenta) to more severe (Jack in the Pulpit, Arisaema) can cause compromised airways. One bite on the Arisaema seed pod will result in immediate swelling and burning. It will take over 12 hours for the swelling to subside .4 – 1 - Treatment Medication administered at the emergency room may include diphenhydramine, epinephrine, or famotidine, all intravenously. Although this most likely will be a localized reaction, it will be treated by the ER as an anaphylactic reaction.
Check Digit Verification of cas no
The CAS Registry Mumber 563-72-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 563-72:
(5*5)+(4*6)+(3*3)+(2*7)+(1*2)=74
74 % 10 = 4
So 563-72-4 is a valid CAS Registry Number.
