Guanine, min. 99 %, for biochemistry, 10 g, glass

Guanine is a purine nucleobase supplied at a minimum purity of 99 % for biochemistry applications. It is identified by CAS number 73-40-5, EG number 200-799-8, empirical formula C₅H₅N₅O and a molar mass of 151,13 g/mol. The product is In biochemical workflows guanine serves as a building block or reference compound when studying base-pairing, metabolic pathways or synthetic routes to nucleotides and related derivatives. Material from Carl ROTH is positioned for laboratory use where consistent assay and transparent identity data are required. The defined purity level supports reproducible preparation of standards and reaction mixtures, while the glass container aids secure storage and handling on the bench. Clear CAS, EG and formula information facilitate inventory control and compliance documentation in research and quality-control settings.
