1-hydroxy-4-methoxy-3,4-dihydropteridin-2(1h)-one 42925-42-8 AR-1C4038 CAS 42925-42-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-hydroxy-4-methoxy-3,4-dihydropteridin-2(1h)-one 42925-42-8 AR-1C4038.

1-hydroxy-4-methoxy-3,4-dihydropteridin-2(1h)-one 42925-42-8 AR-1C4038 (CAS 42925-42-8) is a high-purity analytical reference standard with the molecular formula C4H5ClO2S and a molecular weight of 152.60 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 1-hydroxy-4-methoxy-3,4-dihydropteridin-2(1h)-one 42925-42-8 AR-1C4038 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
