Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-2-(thiophen-2-yl)ethan-1-one.
1-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-2-(thiophen-2-yl)ethan-1-one (CAS 639810-40-5), molecular formula C17H19ClN2OS and molecular weight 334.86 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 1-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-2-(thiophen-2-yl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 1-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-2-(thiophen-2-yl)ethan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
