CAS No.: 119-26-6 Formula: C₆H₆N₄O₄ Formula Weight: 198.14 Linear Formula: (O₂N)₂C₆H₃NHNH₂ MDL No.: MFCD00007578 Purity: ≥99.0% (HPLC) Melting Point: …

…from a variety of organs and animal species. TheOxyIHC test method involves chemical derivatization of protein carbonyl groups with 2,4-dinitrophenylhydrazine (DNPH). This chemical reaction results in proteins being covalently coupled to DNPat their carbonyl sites. The DNP-derivatized proteins…

…and industrial atmospheres. Like traditional DNPH sampling devices, carbonyls (e.g. formaldehyde) are trapped onto our high purity 2,4-dinitrophenylhydrazine (LpDNPH) coated silica gel adsorbent and are converted to form stable hydrazone derivatives but offers the advantage of a 1,2-bis(2-pyridyl)…

…procedures outlined in earlier Method TO-5; the newer method is based on the specific reaction between carbonyl compounds and the 2,4-dinitrophenylhydrazine (DNPH) coating on a silica gel adsorbent (packed in cartridges), in the presence of a strong acid catalyst. The reaction produces stable,…

Sorbent Tube, High-purity Silica Gel (ultra-low background), treated with (2,4-dinitrophenylhydrazine), 6 x 110-mm size, 2 sections, 150/300 mg sorbent, 20/40 mesh, with GS ends and WWW separators, fits Type B tube cover

…Colorimetric Assay is a colorimetric assay for the measurement of oxidized proteins. The carbonyls of protein samples are derivatized using 2,4-dinitrophenylhydrazine. Formation of a Schiff base produces the corresponding hydrazone which can be analyzed spectrophotometrically at 360-385 nm. This…
