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.
CATO supplies Diethyl 2,2'-((5,6,7,8-tetrahydroquinazoline-2,4-diyl)bis(sulfanediyl))diacetate (CAS 1165-85-1), a certified reference material (molecular formula C16H22N2O4S2, MW 370.49 g/mol) for analytical method development and quality control.
The molecular framework of Diethyl 2,2'-((5,6,7,8-tetrahydroquinazoline-2,4-diyl)bis(sulfanediyl))diacetate (C16H22N2O4S2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Diethyl 2,2'-((5,6,7,8-tetrahydroquinazoline-2,4-diyl)bis(sulfanediyl))diacetate 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.
