Description

Compared with other compounds in its class, the molecular weight of 247.25 g/mol gives Ethyl 7-(hydroxyimino)-7,7a-dihydrocyclopropa[b]chromene-1a(1H)-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 7-(hydroxyimino)-7,7a-dihydrocyclopropa[b]chromene-1a(1H)-carboxylate (CAS 179067-99-3), a certified reference material (molecular formula C13H13NO4, MW 247.25 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 7-(hydroxyimino)-7,7a-dihydrocyclopropa[b]chromene-1a(1H)-carboxylate (C13H13NO4) 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 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), Ethyl 7-(hydroxyimino)-7,7a-dihydrocyclopropa[b]chromene-1a(1H)-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.
