  2. 2,4-Dinitrophenylhydrazine - Wikipedia

    en.wikipedia.org/wiki/2,4-Dinitrophenylhydrazine

    2,4-Dinitrophenylhydrazine (2,4-DNPH or DNPH) is the organic compound C 6 H 3 (NO 2) 2 NHNH 2. DNPH is a red to orange solid. It is a substituted hydrazine. The solid is relatively sensitive to shock and friction. For this reason DNPH is usually handled as a wet powder. DNPH is a precursor to the drug Sivifene.

  3. Hydrazines - Wikipedia

    en.wikipedia.org/wiki/Hydrazines

    Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon groups. [1]

    Because it is a computer-based system, IMDS highlights hazardous and controlled substances by comparing entered data with regulatory-originated lists of prohibited substances (GADSL, [3] REACH, ELV, etc...). Hence OEMs can trace hazardous substances back to the individual part and work with suppliers to reduce, control, or eliminate the hazard.

    An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.

  6. 2,4-Dinitrophenol - Wikipedia

    en.wikipedia.org/wiki/2,4-Dinitrophenol

    2,4-Dinitrophenol (2,4-DNP or simply DNP) is an organic compound with the formula HOC 6 H 3 (NO 2) 2. It has been used in explosives manufacturing and as a pesticide and herbicide. In humans, DNP causes dose-dependent mitochondrial uncoupling , causing the rapid loss of ATP as heat and leading to uncontrolled hyperthermia —up to 44 °C (111 ...

    Frederick Sanger. In 1945, Frederick Sanger described its use for determining the N-terminal amino acid in polypeptide chains, in particular insulin. [4] Sanger's initial results suggested that insulin was a smaller molecule than previously estimated (molecular weight 12,000), and that it consisted of four chains (two ending in glycine and two ending in phenylalanine), with the chains cross ...

    If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:GHS templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:GHS templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last ...
