Methyl 5-(furan-3-yl)oxazole-4-carboxylate CAS 88352-88-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5-(furan-3-yl)oxazole-4-carboxylate.

Methyl 5-(furan-3-yl)oxazole-4-carboxylate (CAS 88352-88-9), molecular formula C9H7NO4 and molecular weight 193.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 5-(furan-3-yl)oxazole-4-carboxylate (C9H7NO4) is characterized by an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Methyl 5-(furan-3-yl)oxazole-4-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.
