3,4-Dihydro-2h-1-benzopyran-6-sulfonic acid CAS 127461-58-9

Description

The occurrence of 3,4-Dihydro-2h-1-benzopyran-6-sulfonic acid is closely related to a sulfone group, 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.

CATO supplies 3,4-Dihydro-2h-1-benzopyran-6-sulfonic acid (CAS 127461-58-9), a certified reference material (molecular formula C9H10O4S, MW 214.24 g/mol) for analytical method development and quality control.

The molecular framework of 3,4-Dihydro-2h-1-benzopyran-6-sulfonic acid (C9H10O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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), 3,4-Dihydro-2h-1-benzopyran-6-sulfonic acid 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.
