4-Nitrophenyl-N-acetyl-beta-D-, galactosaminide, min. 98 %, biochemistry, 250 mg

4-Nitrophenyl-N-acetyl-β-D-galactosaminide is a biochemistry reagent supplied at a minimum purity of 98 %. It is registered under CAS number 14948-96-0 and EG nr. 239-024-3, with the empirical formula C₁₄H₁₈N₂O₈ and a molar mass of 342,31 g/mol. The nitrophenyl glycoside structure provides a well-characterised substrate identity for laboratory documentation and experimental planning. Nitrophenyl-N-acetylgalactosaminide derivatives are used in enzymatic biochemistry where a defined glycoside substrate supports activity measurements and related analytical work. This grade from manufacturer Carl ROTH is intended for biochemistry applications that require consistent purity and clear molecular specification. The combination of high minimum assay, established identifiers, and a convenient mid-size pack supports both specialised investigations and routine laboratory workflows involving N-acetyl-β-D-galactosaminide substrates.
