Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzyl (5-(4-chlorophenyl)oxazol-2-yl)carbamate.
Benzyl (5-(4-chlorophenyl)oxazol-2-yl)carbamate (CAS 13575-29-6), molecular formula C17H13ClN2O3 and molecular weight 328.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzyl (5-(4-chlorophenyl)oxazol-2-yl)carbamate (C17H13ClN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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), Benzyl (5-(4-chlorophenyl)oxazol-2-yl)carbamate 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.
