CAS 33404-34-1 — D-(+)-Cellotriose

D-(+)-Cellotriose is a trisaccharide composed of three β-1,4-linked D-glucose units, commonly used as a substrate in enzymatic and biochemical research to study cellulase activity, glycoside hydrolase function, and carbohydrate metabolism. It appears as a white to off-white powder, highly soluble in water but insoluble in organic solvents. This chemical has a CAS number of 33404-34-1, molecular formula C18H32O16, and a molecular weight of 504.44 g/mol. It carries no signal word under standard hazard classifications and must be stored at -15 to -20°C to preserve stability. Molekula supplies D-(+)-Cellotriose from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
