[NamRa]

Hello.
I have 2 options for Heptane.

Which one is prefered to use and why ?

Thanks, NamRa;

Heptane (isomer) ≥98,5 %, for synthesis

Empirical formula C7H16
Molar mass (M) 100,21 g/mol
Density (D) 0,71
Boiling point (bp) 94-100 °C
Flash point (flp)-4 °C
ADR 3 II • WGK 3
UN-Nr. 1206

n-Heptane ≥95 %, for synthesis

Methyl hexane, 1-Methyl hexane
Empirical formula C7H16
Molar mass (M) 100,20 g/mol
Density (D) 0,69 g/cm³
Boiling point (bp) 98,4 °C
Flash point (flp) -4 °C
Melting point (mp) -90,5 °C
ADR 3 II
WGK 2
CAS No. [142-82-5]
EG-Nr. 205-563-8
UN-Nr. 1206

Both are good so pick the cheapest option. Probably the one with the strange isomers of 1-Methyl hexane which is just heptane.
