Chemical Structure

D-(+)-Cellotriose CAS 33404-34-1 chemical structure

Description

D-(+)-Cellotriose (CAS 33404-34-1), molecular formula C18H32O16 and molecular weight 504.44 g/mol, is a CATO reference standard with documented purity and traceability.

D-(+)-Cellotriose (C18H32O16) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), D-(+)-Cellotriose meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
