Description
Polypropylene glycol 2000 is a p.a. grade polymer reagent with CAS number 25322-69-4 and empirical formula [C₃H₆O]ₙ. The material has a molar mass of 2000 g/mol, a density of 1,004 g/cm³, a flash point above 100 °C and a boiling range of 288 to 310 °C, making its physical profile clear for laboratory planning. The p.a. specification supports use where higher purity reagents are preferred for reproducible results. This product from manufacturer Carl ROTH belongs to the polypropylene glycols (PPG) family used as polymer and monomer building blocks in performance materials research and development. The glass bottle presentation protects the liquid during storage and handling on the bench. Clear identity data—including CAS number, molar mass and density—help laboratories document methods and material specifications accurately.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Polypropylene glycol 2000, p.a., 250 ml, glass
What is this article?
Polypropylene glycol 2000, p.a., 250 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
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 Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents 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.
