Chemical Structure

(NE)-N-[1-(phenylmethoxyamino)propylidene]carbamic acid methyl ester 345-89-1 A822298 methyl (NE)-N-[1-(phenylmethoxyamino)propylidene]carbamate CAS 345-89-1 chemical structure

Description

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.

(NE)-N-[1-(phenylmethoxyamino)propylidene]carbamic acid methyl ester 345-89-1 A822298 methyl (NE)-N-[1-(phenylmethoxyamino)propylidene]carbamate (CAS 345-89-1), molecular formula C14H23FO2 and molecular weight 242.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (NE)-N-[1-(phenylmethoxyamino)propylidene]carbamic acid methyl ester 345-89-1 A822298 methyl (NE)-N-[1-(phenylmethoxyamino)propylidene]carbamate (C14H23FO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), (NE)-N-[1-(phenylmethoxyamino)propylidene]carbamic acid methyl ester 345-89-1 A822298 methyl (NE)-N-[1-(phenylmethoxyamino)propylidene]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.
