Chemical Structure

Methyl 2-(Cbz-amino)-2-[1,1-dioxidodihydro-2H-thiopyran-4(3H)-ylidene]acetate CAS 894790-19-3 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 Methyl 2-(Cbz-amino)-2-[1,1-dioxidodihydro-2H-thiopyran-4(3H)-ylidene]acetate.

Methyl 2-(Cbz-amino)-2-[1,1-dioxidodihydro-2H-thiopyran-4(3H)-ylidene]acetate (CAS 894790-19-3) is a high-purity analytical reference standard with the molecular formula C16H19NO6S and a molecular weight of 353.39 g/mol.

The molecular framework of Methyl 2-(Cbz-amino)-2-[1,1-dioxidodihydro-2H-thiopyran-4(3H)-ylidene]acetate (C16H19NO6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Methyl 2-(Cbz-amino)-2-[1,1-dioxidodihydro-2H-thiopyran-4(3H)-ylidene]acetate 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.
