Description
Glutaraldehyde 50 %, in water is an aqueous aldehyde solution intended for electron microscopy workflows. It is identified by CAS number 111-30-8 and EG nr. 203-856-5, with a molar mass of 100,12 g/mol and a density of 1,13 g/cm³. The boiling range is given as 100 to 102 °C and the flash point exceeds 100 °C, supporting controlled handling in fixation and sample-preparation steps. Physical data from manufacturer Carl ROTH allow straightforward integration into existing reagent inventories and risk assessments. Typical use centres on specimen fixation and related electron-microscopy preparation, where a defined 50 % aqueous concentration helps standardise working dilutions. The material is listed under UN number 2927, so transport and storage planning should follow the corresponding hazardous-goods guidance. Overall, the combination of stated concentration, clear physicochemical parameters and microscopy-oriented positioning makes this a practical choice for EM laboratories needing a reliable glutaraldehyde stock solution.

Questions about Glutaraldehyde 50 %, in water, for electron microscopy, 500 ml, plastic
What is this article?
Glutaraldehyde 50 %, in water, for electron microscopy, 500 ml, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Produits chimiques de laboratoire et industriels.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
