2,2'-(Tetrahydro-2H-pyran-4,4-diyl)diacetic acid CAS 110796-49-1

Description

The occurrence of 2,2'-(Tetrahydro-2H-pyran-4,4-diyl)diacetic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,2'-(Tetrahydro-2H-pyran-4,4-diyl)diacetic acid (CAS 110796-49-1), a certified reference material (molecular formula C9H14O5, MW 202.20 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,2'-(Tetrahydro-2H-pyran-4,4-diyl)diacetic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.20 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), 2,2'-(Tetrahydro-2H-pyran-4,4-diyl)diacetic 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.
