2,3-dihydro-4H-thiochromen-4-one 3528-17-4 4H-1-benzothiopyran-4-one, 2,3-dihydro- InChI=1/C9H8OS/c10-8-5-6-11-9-4-2-1-3-7(8)9/h1-4H,5-6H CAS 3528-17-4 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 2,3-dihydro-4H-thiochromen-4-one 3528-17-4 4H-1-benzothiopyran-4-one, 2,3-dihydro- InChI=1/C9H8OS/c10-8-5-6-11-9-4-2-1-3-7(8)9/h1-4H,5-6H.

CATO supplies 2,3-dihydro-4H-thiochromen-4-one 3528-17-4 4H-1-benzothiopyran-4-one, 2,3-dihydro- InChI=1/C9H8OS/c10-8-5-6-11-9-4-2-1-3-7(8)9/h1-4H,5-6H (CAS 3528-17-4), a certified reference material (molecular formula C9H14OS, MW 170.27 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, 2,3-dihydro-4H-thiochromen-4-one 3528-17-4 4H-1-benzothiopyran-4-one, 2,3-dihydro- InChI=1/C9H8OS/c10-8-5-6-11-9-4-2-1-3-7(8)9/h1-4H,5-6H is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.27 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.
