Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-[1-(4-Methylbenzoyl)-3-(trifluoromethyl)-1H-pyrazol-4-yl]propyl 4-methylbenzoate.
3-[1-(4-Methylbenzoyl)-3-(trifluoromethyl)-1H-pyrazol-4-yl]propyl 4-methylbenzoate (CAS 318237-85-3) is a high-purity analytical reference standard with the molecular formula C23H21F3N2O3 and a molecular weight of 430.42 g/mol.
3-[1-(4-Methylbenzoyl)-3-(trifluoromethyl)-1H-pyrazol-4-yl]propyl 4-methylbenzoate (C23H21F3N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3-[1-(4-Methylbenzoyl)-3-(trifluoromethyl)-1H-pyrazol-4-yl]propyl 4-methylbenzoate 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.
