(2R,3S,4S,5R,6R)-2-(acetoxymethyl)-6-(2-chloroethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate CAS 140428-85-9 chemical structure

Description

CATO supplies (2R,3S,4S,5R,6R)-2-(acetoxymethyl)-6-(2-chloroethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 140428-85-9), a certified reference material (molecular formula C16H23ClO10, MW 410.80 g/mol) for analytical method development and quality control.

Structurally, (2R,3S,4S,5R,6R)-2-(acetoxymethyl)-6-(2-chloroethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (C16H23ClO10) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 410.80 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).

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), (2R,3S,4S,5R,6R)-2-(acetoxymethyl)-6-(2-chloroethoxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate 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.
