General description

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.

Application


  • Commercial formaldehyde standard for mass calibration in mass spectrometry.: This study evaluates the use of a commercial formaldehyde standard in mass spectrometry for precise mass calibration, emphasizing its role in enhancing measurement accuracy in pharmaceutical research and biochemistry labs (Lyczko et al., 2015).

  • Honey as a substitute for formalin: This research investigates honey as a potential substitute for formaldehyde in biochemistry applications, comparing its effects on tissue preservation and staining qualities, which may influence biochemistry assays and lab practices (Ozkan et al., 2012).

Questions

1–5 of 5 Questions  

  1. Does this product already contain 2,4-DNPH or has 2,4-DNPH only been added to the product for CoA testing?

    1 answer

    1. This product does not contain 2,4-Dinitrophenylhydrazine (2,4 DNPH). (2,4 DNPH) was used as a derivatizing agent for QC analysis.

      Helpful?

  2. Why there are 2,4-DNPH and Formaldehyde-2,4-DNPH on HPLC result in CoA? Why there is no Formaldehyde on the result of HPLC.

    1 answer

    1. Formaldehyde cannot be detected by HPLC without derivatization. Therefore, the formaldehyde-DNPH is the derivatized material and is what is being analyzed and reported. The 2,4-DNPH is the excess derivatizing agent.

  3. Does Product ICS045 contain methanol as a stabilizer?

    1 answer

    1. This product does have methanol in it

  4. The CoA for the lot purchased lists the raw material potency as 35.2%, what is the purpose of this value? If I want to make a calibration curve using this, do I need to take this number into account? Or am I just using the 1000 mg/L for calculations?

    1 answer

    1. Raw material purity is included for traceability to the raw material. In some cases, it can also explain any low-level impurities that a customer might see in the provided chromatogram. Please use the certified value directly. No correction of the certified value is needed. It has already been corrected for the raw material purity.

      Helpful?

  5. hola, con respecto al producto ICS045, me gustaría saber que concentración tiene de formaldehído, puesto que en la información del producto pone 1000ug/ml y en el certificado de origen de ejemplo que se puede descargar, pone 1000mg/l.

    1 answer

    1. As listed in the properties section on the website, the concentration is 1000 μg/mL in H2O. The 1000 μg/mL may be converted to 1 mg/mL. Thus, the 1000mg/L reported in the Certificate is also correct.
