Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2-Methoxybenzyl)-5-oxo-2,3-dihydro-5H-thiazolo[2,3-b]quinazoline-8-carboxamide.
N-(2-Methoxybenzyl)-5-oxo-2,3-dihydro-5H-thiazolo[2,3-b]quinazoline-8-carboxamide (CAS 1251647-47-8) is a high-purity analytical reference standard with the molecular formula C19H17N3O3S and a molecular weight of 367.42 g/mol.
Structurally, N-(2-Methoxybenzyl)-5-oxo-2,3-dihydro-5H-thiazolo[2,3-b]quinazoline-8-carboxamide (C19H17N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 367.42 g/mol, it falls into the moderately-high-molecular-weight range. 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), N-(2-Methoxybenzyl)-5-oxo-2,3-dihydro-5H-thiazolo[2,3-b]quinazoline-8-carboxamide 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.
