4-Ethyl-4-methyldihydro-2H-pyran-2,6(3H)-dione CAS 6970-57-6

Description

CATO supplies 4-Ethyl-4-methyldihydro-2H-pyran-2,6(3H)-dione (CAS 6970-57-6), a certified reference material (molecular formula C8H12O3, MW 156.18 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4-Ethyl-4-methyldihydro-2H-pyran-2,6(3H)-dione is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.18 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), 4-Ethyl-4-methyldihydro-2H-pyran-2,6(3H)-dione 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.
