Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,3S,4S,5R,6S)-3,4,5-tris(benzyloxy)-2-(iodomethyl)-6-methoxytetrahydro-2H-pyran.

(2S,3S,4S,5R,6S)-3,4,5-tris(benzyloxy)-2-(iodomethyl)-6-methoxytetrahydro-2H-pyran (CAS 85716-43-4) is a high-purity analytical reference standard with the molecular formula C28H31IO5 and a molecular weight of 574.45 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, iodine substitution, (2S,3S,4S,5R,6S)-3,4,5-tris(benzyloxy)-2-(iodomethyl)-6-methoxytetrahydro-2H-pyran is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 574.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (2S,3S,4S,5R,6S)-3,4,5-tris(benzyloxy)-2-(iodomethyl)-6-methoxytetrahydro-2H-pyran 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.
