Chemical Structure

(2R,3R)-Butane-2,3-diyl bis(4-methylbenzenesulfonate) CAS 64896-27-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,3R)-Butane-2,3-diyl bis(4-methylbenzenesulfonate).

(2R,3R)-Butane-2,3-diyl bis(4-methylbenzenesulfonate) (CAS 64896-27-1), molecular formula C18H22O6S2 and molecular weight 398.49 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, (2R,3R)-Butane-2,3-diyl bis(4-methylbenzenesulfonate) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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,3R)-Butane-2,3-diyl bis(4-methylbenzenesulfonate) 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.
