Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-3-4-Tri-O-benzyl-β-D-arabinopyranose (CAS 18039-26-4), a certified reference material (molecular formula C26H28O5, MW 420.50 g/mol) for analytical method development and quality control.
Structurally, 2-3-4-Tri-O-benzyl-β-D-arabinopyranose (C26H28O5) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 420.50 g/mol, it falls into the moderately-high-molecular-weight range. 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).
As a certified reference material (CRM), 2-3-4-Tri-O-benzyl-β-D-arabinopyranose 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.
