Methyl 1-((2-bromo-4-chlorophenoxy)methyl)-1h-pyrazole-3-carboxylate CAS 1001500-31-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 345.58 g/mol gives Methyl 1-((2-bromo-4-chlorophenoxy)methyl)-1h-pyrazole-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 1-((2-bromo-4-chlorophenoxy)methyl)-1h-pyrazole-3-carboxylate (CAS 1001500-31-7), molecular formula C12H10BrClN2O3 and molecular weight 345.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 1-((2-bromo-4-chlorophenoxy)methyl)-1h-pyrazole-3-carboxylate (C12H10BrClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
