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
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. 2-Methoxyethanol is widely used solvent in various electrochemical studies and industrial processes. It exhibits "quasi-aprotic" properties. Its solvent characteristics are a mixture of that of protic and aprotic solvents.
This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)
Other Notes
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Meniscus reconstruction is in great need for orthopedic surgeons. Meniscal fibrochondrocytes transplantation was proposed to regenerate functional meniscus, with limited donor supply. We hypothesized that coculture of synovial mesenchymal stem cells (SSC) with meniscal fibrochondrocytes (me-CH) can support matrix production

A new complex of 1-hydroxy-4-(prop-2-enyloxy)-9,10-anthraquinone and Y(III) was synthesized and used as the functional monomer for a novel Y(III) nanostructure ion-imprinted polymer. This polymer was used as a sorbent for fast and selective separation. The separation method was based on

Controlled density semiconducting oxide arrays are highly desirable for matching nanometer length scales specific to emerging applications. This work demonstrates a facile one-step method for templating hydrothermal growth which provides arrays with high-fidelity tuning of nanorod spacing and diameter. This
