methyl 2-azido-3-[4-chloro-2-(difluoromethoxy)phenyl]prop-2-enoate CAS 2755782-71-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including methyl 2-azido-3-[4-chloro-2-(difluoromethoxy)phenyl]prop-2-enoate.

methyl 2-azido-3-[4-chloro-2-(difluoromethoxy)phenyl]prop-2-enoate (CAS 2755782-71-7) is a high-purity analytical reference standard with the molecular formula C11H14ClF2N3O3 and a molecular weight of 309.70 g/mol.

The molecular framework of methyl 2-azido-3-[4-chloro-2-(difluoromethoxy)phenyl]prop-2-enoate (C11H14ClF2N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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), methyl 2-azido-3-[4-chloro-2-(difluoromethoxy)phenyl]prop-2-enoate 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.
