(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)(4-chlorophenyl)methanol CAS 956507-62-3

Description

(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)(4-chlorophenyl)methanol (CAS 956507-62-3) is a high-purity analytical reference standard with the molecular formula C17H14Cl2N2O and a molecular weight of 333.21 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)(4-chlorophenyl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.21 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), (5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)(4-chlorophenyl)methanol 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.
