Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 359.73 g/mol gives Methyl (5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-methylphenyl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl (5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-methylphenyl)carbamate (CAS 866153-11-9), molecular formula C16H13ClF3NO3 and molecular weight 359.73 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Methyl (5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-methylphenyl)carbamate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-methylphenyl)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.
