Chemical Structure

1-Methylcyclohepta[b]pyrrol-2(1H)-one CAS 3336-87-6 chemical structure

Description

As a certified reference material (CRM), 1-Methylcyclohepta[b]pyrrol-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.

1-Methylcyclohepta[b]pyrrol-2(1H)-one (CAS 3336-87-6), molecular formula C10H9NO and molecular weight 159.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Methylcyclohepta[b]pyrrol-2(1H)-one (C10H9NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
