Description
Dichloromethane, PEPTIPURE® is a high-purity solvent with a minimum assay of 99,9 % intended for peptide synthesis, including washing, deprotection, and related process steps. Stabilised with amylene, it offers the empirical formula CH₂Cl₂, CAS number 75-09-2, EG number 200-838-9, and a molar mass of 84,93 g/mol. Reported physical properties include a density of 1,33 g/cm³ and a boiling point of 40 °C, which are characteristic of dichloromethane used in organic and peptide chemistry. The PEPTIPURE® grade from manufacturer Carl ROTH supports demanding peptide-synthesis reagent requirements where solvent quality is critical for coupling cycles and intermediate handling. Supplied in a 2,5 l glass pack, the solvent suits medium-scale laboratory synthesis and routine process use. UN number 1593 identifies the material for compliant transport and storage planning. This dichloromethane grade is positioned for laboratories performing peptide synthesis and associated organic washing or deprotection operations that specify PEPTIPURE® quality dichloromethane.

Questions about Dichloromethane, PEPTIPURE®, min. 99,9 %, for peptide synthesis, 2.5 l, glass
What is this article?
Dichloromethane, PEPTIPURE®, min. 99,9 %, for peptide synthesis, 2.5 l, 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.
