Description

The occurrence of (2R,3R,4S,5S,6R)-2-(((2R,3S,4R,5R,6R)-6-(((2R,3S,4R,5R,6R)-4,5-dihydroxy-2-(hydroxymethyl)-6-(((2R,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-3-yl)oxy)-4,5-dihydroxy-2-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2R,3R,4S,5S,6R)-2-(((2R,3S,4R,5R,6R)-6-(((2R,3S,4R,5R,6R)-4,5-dihydroxy-2-(hydroxymethyl)-6-(((2R,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-3-yl)oxy)-4,5-dihydroxy-2-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (CAS 25545-20-4) is a high-purity analytical reference standard with the molecular formula C24H42O21 and a molecular weight of 666.58 g/mol.

(2R,3R,4S,5S,6R)-2-(((2R,3S,4R,5R,6R)-6-(((2R,3S,4R,5R,6R)-4,5-dihydroxy-2-(hydroxymethyl)-6-(((2R,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-3-yl)oxy)-4,5-dihydroxy-2-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (C24H42O21) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (2R,3R,4S,5S,6R)-2-(((2R,3S,4R,5R,6R)-6-(((2R,3S,4R,5R,6R)-4,5-dihydroxy-2-(hydroxymethyl)-6-(((2R,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-3-yl)oxy)-4,5-dihydroxy-2-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol 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.
