Description
Petroleum benzine 135-180 is an extra pure hydrocarbon solvent fraction with a boiling range of 140 to 164 °C and CAS number 64742-82-1. It has a density of 0,775 g/cm³ and a flash point of 29 °C, placing it among flammable mid-range petroleum solvents used in the laboratory. Manufacturer Carl ROTH supplies this extra pure quality with EG number 927-344-2 for routine chemical and industrial laboratory applications. The defined boiling interval supports controlled evaporation and residual handling where lighter fractions would flash off too quickly. Transport identification is UN number 3295. Select this cut when moderate volatility and consistent density are needed for organic work-up or solvent exchange. Observe flammable-liquid precautions, ensure adequate ventilation, and consult the safety data sheet prior to use.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Petroleum benzine 135-180, extra pure, 1 l, glass
What is this article?
Petroleum benzine 135-180, extra pure, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Technical & synthesis grade solvents, inside Solvents, in Lab chemicals.
Technical and synthesis grades are for cleaning, for a coarse extraction and for chemistry that does not end in a chromatogram. They cost less because more impurity is allowed. They are the wrong bottle to make a mobile phase or a volumetric standard.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Technical & synthesis grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis) and Green & alternative solvents.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
