2,4-Dichloro-3-(3-pyrrolinomethyl) benzophenone CAS 898749-50-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Dichloro-3-(3-pyrrolinomethyl) benzophenone.

2,4-Dichloro-3-(3-pyrrolinomethyl) benzophenone (CAS 898749-50-3) is a high-purity analytical reference standard with the molecular formula C18H15Cl2NO and a molecular weight of 332.22 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2,4-Dichloro-3-(3-pyrrolinomethyl) benzophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,4-Dichloro-3-(3-pyrrolinomethyl) benzophenone 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.
