Chemical Structure
Description
The occurrence of 2-{4-[(4-methoxyphenyl)methyl]piperazin-1-yl}-1,3-benzothiazole is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-{4-[(4-methoxyphenyl)methyl]piperazin-1-yl}-1,3-benzothiazole (CAS 256475-43-1), a certified reference material (molecular formula C19H21N3OS, MW 339.45 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-{4-[(4-methoxyphenyl)methyl]piperazin-1-yl}-1,3-benzothiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.45 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.
CATO manufactures 2-{4-[(4-methoxyphenyl)methyl]piperazin-1-yl}-1,3-benzothiazole 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.
