1-Hydroxyethylidene-1,1-Diphosphonic Acid, commonly known as HEDP or Etidronic acid, bears the CAS number 2809-21-4.
This versatile molecule features a molecular formula of C₂H₈O₇P₂ and molar mass at 206.03 grams per mole.
With density around 1.45 for a 60% aqueous solution, this substance exhibits properties including melting point between 198-199°C and high stability against chlorine degradation.
As a crucial industrial chemical, HEDP functions primarily as a boiler and heat exchange system's scale inhibitor and anticorrosive additive.
Its applications also extend beyond these domains – serving as a stabilizer in soaps, cleanser for metals and non-metals, electroplating complexing agent without cyanide, textile fixing aid, concrete retardant, cooling systems descalant, carbonated waters preservative, construction material enhancer, and even as a peroxide stabilizer.
A key advantage lies within its ability to create durable bonds with various metallic elements, making it suitable for combined treatments alongside additional agents like phosphates, polymers, and salts.
Although considered less toxic overall, contact with concentrated solutions may cause eye and skin irritation necessitating immediate flushing if accidental contamination occurs.
Proper protective gear during handling ensures safety from any unintended harm due to prolonged exposures.
Additionally, maintaining adequate air circulation when storing bulk quantities helps prevent undue deterioration caused by sunlight or extreme temperature fluctuations.
Lastly, exercise care when mixing different chemicals since certain combinations could lead to unwanted reactions.
1-Hydroxyethylidene-1,1-Diphosphonic Acid stands out owing to its multitude of uses spanning numerous industry segments coupled with reasonable health risks provided appropriate precautions are taken throughout production processes and end application scenarios alike.away from sunlight, and avoid mixing with strong alkalines.
