Oxazolo[4,5-d]pyrimidine CAS 42850-93-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Oxazolo[4,5-d]pyrimidine.

Oxazolo[4,5-d]pyrimidine (CAS 42850-93-1), molecular formula C5H3N3O and molecular weight 121.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Oxazolo[4,5-d]pyrimidine (C5H3N3O) is characterized by an amide 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).

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), Oxazolo[4,5-d]pyrimidine 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.
