Description

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.

Methyl 2-imino-10-methyl-5-oxo-1-(pyridin-3-ylmethyl)-2,5-dihydro-1H-dipyrido[1,2-a:2',3'-d]pyrimidine-3-carboxylate (CAS 370869-55-9) is a high-purity analytical reference standard with the molecular formula C20H17N5O3 and a molecular weight of 375.38 g/mol.

Structurally, Methyl 2-imino-10-methyl-5-oxo-1-(pyridin-3-ylmethyl)-2,5-dihydro-1H-dipyrido[1,2-a:2',3'-d]pyrimidine-3-carboxylate (C20H17N5O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 375.38 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).

As a certified reference material (CRM), Methyl 2-imino-10-methyl-5-oxo-1-(pyridin-3-ylmethyl)-2,5-dihydro-1H-dipyrido[1,2-a:2',3'-d]pyrimidine-3-carboxylate 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.
