Chemical Structure

1-Benzyl-5-chloro-3-methyl-6-phenylpyrazin-2(1H)-one CAS 173199-87-6 chemical structure

Description

1-Benzyl-5-chloro-3-methyl-6-phenylpyrazin-2(1H)-one (CAS 173199-87-6), molecular formula C18H15ClN2O and molecular weight 310.78 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Benzyl-5-chloro-3-methyl-6-phenylpyrazin-2(1H)-one (C18H15ClN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 310.78 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 1-Benzyl-5-chloro-3-methyl-6-phenylpyrazin-2(1H)-one 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.
