Chemical Structure

N-[4-(benzyloxy)-3-methoxybenzyl]-2-chloro-N-methylacetamide CAS 923752-67-4 chemical structure

Description

N-[4-(benzyloxy)-3-methoxybenzyl]-2-chloro-N-methylacetamide (CAS 923752-67-4) is a high-purity analytical reference standard with the molecular formula C18H20ClNO3 and a molecular weight of 333.81 g/mol.

The molecular framework of N-[4-(benzyloxy)-3-methoxybenzyl]-2-chloro-N-methylacetamide (C18H20ClNO3) 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 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), N-[4-(benzyloxy)-3-methoxybenzyl]-2-chloro-N-methylacetamide 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.
