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 4-(Benzyloxy)-3-hydroxybenzyl Alcohol 3-p-Toluenesulfonate.
4-(Benzyloxy)-3-hydroxybenzyl Alcohol 3-p-Toluenesulfonate (CAS 65615-21-6) is a high-purity analytical reference standard with the molecular formula C21H20O5S and a molecular weight of 384.45 g/mol.
The molecular framework of 4-(Benzyloxy)-3-hydroxybenzyl Alcohol 3-p-Toluenesulfonate (C21H20O5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-(Benzyloxy)-3-hydroxybenzyl Alcohol 3-p-Toluenesulfonate 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.
