Heptane

Description :
Heptane est un alcane à chaîne droite avec la formule moléculaire C7H16, caractérisé par ses sept atomes de carbone et les atomes d'hydrogène correspondants. C'est un liquide incolore et inflammable à température ambiante, avec une odeur distinctive rappelant l'essence. Heptane est insoluble dans l'eau mais soluble dans les solvants organiques, ce qui le rend utile dans diverses applications, y compris comme solvant non polaire dans les laboratoires et comme standard de référence dans les tests d'octane pour les carburants. Son point d'ébullition est relativement bas par rapport aux alcanes plus grands, et il présente une haute pression de vapeur, contribuant à sa volatilité. Heptane est classé comme un hydrocarbure et fait partie de la série des alcanes, qui sont des composés saturés avec des liaisons simples entre les atomes de carbone. En raison de son inflammabilité, il doit être manipulé avec précaution et présente des risques pour la santé s'il est inhalé ou ingéré. En termes de réactivité, Heptane subit des réactions typiques des alcanes, telles que la combustion, produisant du dioxyde de carbone et de l'eau. Son numéro CAS, 142-82-5, est un identifiant unique utilisé à des fins réglementaires et de sécurité.

  • Reagecon Fatty Acid Methyl Ester (FAME) 8 Compound Mix Method A Reference Solution in n-Heptane according to European Pharmacopoeia (EP) Chapter 2.4.22, Table 3

    CAS :
    This Reagecon Fatty Acid Methyl Ester (FAME) 8 Compound Mix is a ready to use product that is used either as a calibrant or analytical control solution for a variety of gas and liquid chromatography methods that include GC; GC-MS; HPLC and LC-MS. This product can also be used to validate appropriate test methods or qualify an instrument in a regulated industry. - The identity of each standard is verified using a high performance calibrated Gas Chromatograph Mass Spectrometer (GC-MS Instrument). The mass spectrum of each of the analytes is confirmed by comparison with the National Institute of Standards and Technology (NIST) mass spectral library. - The esterification of fatty acids is an important tool for both characterising fats and oils and for determining the total fat content in foods and foodstuffs. It is also an important measurement for the assessing of quality and purity of biofuels. Description | Concentration: - Methyl Myristate: 10% w/w. - Methyl Palmitate: 15% w/w. - Methyl Stearate: 20% w/w. - Methyl Arachidate: 20% w/w. - Methyl Oleate: 10% w/w. - Methyl Eicosenoate: 5% w/w. - Methyl Behenate: 10% w/w. - Methyl Linocerate: 10% w/w.
