After releasing the chlorinated phenol and resin acid standards last month, Alfa Chemistry announces to further diversify its supply of environmental goods standards by adding a new type—drinking water disinfection byproducts standards, which can be used in the R&D to better drinking water disinfection methods.
As new technologies and applications to study environmental, food, water and exposure contaminants advance, CIL continues to maintain a leadership role working with researchers to develop new standards to meet the latest needs. With new instrumentation and extraction procedures allowing detection limits approaching attogram levels in some cases, the need for highly accurate isotope standards has never been greater.

Currently phthalate monoesters that are breakdown products of phthalate diesters, ubiquitous environmental contaminants. As the most important polymer additives, the amount of phthalate esters in WIP ranged from 0 to 50%. Phthalate esters are one of the most frequently detected persistent organic pollutants in the environment. The environmental contaminants standards we supplied is mainly series phthalate monoesters.
“Disinfectants can react with naturally-occurring materials in the water, which result in the formation of byproducts such as THM, HAA, chlorite, and bromate. Exposure to these byproducts can possibly lead to cancer and therefore should be carefully limited,” says a spokesperson from Alfa Chemistry. “To reduce the levels of contaminants in drinking water, primary standards and treatment techniques are employed. For example, it is suggested that prior to disinfection, conventional filtration treatments are required to remove specified percentages of organic materials that may react with disinfectants to form disinfection byproducts. Other control strategies include modification of disinfection practices in a manner that still provides adequate protection against pathogens.”
To facilitate scientists’ exploration of better ways to reduce the occurrence of disinfection byproducts, Alfa Chemistry offers high quality standards for analytical or reference use.
The drinking water disinfection byproduct standards supplied by Alfa Chemistry include a range of haloketones, halonitromethanes, halomethanes, haloaldehydes, haloacids, haloacetonitriles and haloacetamides. Below are just some of them:
All products at Alfa Chemistry are strictly QC assessed so that high quality is guaranteed. Technique documents such as COA are also provided.
