Analysis Note
These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.
Application
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
General description
2-ethoxyethanol is a glycol ether commonly utilized for applications such as paints, inks, cleaners, polishes, solvents, as well as chemical intermediates. It has been reported as a precursor for ethoxyacetic acid (EAA).
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Water-soluble phosphorescent polymeric nanoparticles with an average diameter of approximately 100 nm were synthesized by a coordination cross-linking reaction. The pyridine blocks in poly(4-vinyl pyridine-b-ethylene oxide) (P4VP-b-PEO) were cross-linked by the iridium chloride-bridged dimer in DMF solution. Owing to the presence
