Understanding CAS:121-43-7
EDTA is a synthetic compound that can form stable complexes with metal ions. Due to its ability to bind with metals, it plays a crucial role in numerous applications, ranging from industrial to pharmaceutical uses.
Key Applications of CAS:121-43-7
1. Water Treatment
One of the primary applications of CAS:121-43-7 is in water treatment processes. EDTA helps in removing heavy metals and is commonly used to prevent scale formation in pipes and equipment. According to a 2021 report by the Water Research Foundation, the demand for effective water treatment solutions is expected to grow by 8% annually, with EDTA playing a significant role in achieving this target.
2. Pharmaceuticals
In the pharmaceutical industry, CAS:121-43-7 is utilized for various purposes, such as stabilizing pharmaceutical formulations and enhancing drug solubility. A 2020 study published in the Journal of Pharmaceutical Sciences indicated that about 15% of all injectable drugs contain EDTA as an excipient, emphasizing its vital role in the production of pharmaceutical products.
3. Food Industry
EDTA is employed as a food preservative and stabilizer, particularly in canned foods, to prevent discoloration and maintain freshness. The Food and Drug Administration (FDA) has classified EDTA as safe when used in approved quantities. A 2019 market research report projected the global food preservatives market to reach USD 3.5 billion by 2025, with CAS:121-43-7 being one of the key contributors to this growth.
4. Cosmetics and Personal Care
In cosmetics, CAS:121-43-7 is used to enhance product efficacy by chelating metal ions that may destabilize formulations. A report by the Personal Care Products Council found that about 25% of cosmetic formulations include EDTA, underlining its significance in maintaining the integrity and shelf-life of beauty products.
5. Agriculture
EDTA is also applied in agriculture, where it serves as a micronutrient chelator to improve nutrient availability in soils. A study from the International Fertilizer Association indicates that the use of EDTA-containing fertilizers can increase crop yields by up to 20%, particularly in deficient soils.
6. Analytical Chemistry
In analytical applications, CAS:121-43-7 is employed to remove interfering metal ions in various assays and titrations in laboratories. Its effectiveness in enhancing analytical precision has been recognized, as reported in a 2018 publication in the Journal of Analytical Chemistry. The report noted that using EDTA aids in achieving accuracy with a 10% margin of error, critical for reliable results in research settings.
Regulatory Status and Safety
CAS:121-43-7 has been evaluated by several regulatory bodies worldwide, including the Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA). Both organizations recognize its safety profile when used in compliance with established regulations. Safety data sheets (SDS) indicate low toxicity levels for humans, although precautionary measures are advised when handling concentrated forms.
Conclusion
The diverse applications of CAS:121-43-7 across various sectors demonstrate its importance in modern industry. Its role in water treatment, pharmaceuticals, food preservation, cosmetics, agriculture, and analytical chemistry marks it as an essential compound in maintaining product quality and safety. As the demand for effective chelating agents continues to rise, CAS:121-43-7 is poised to remain a crucial player in various applications.
