Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-((3-Chloro-4-fluorophenyl)sulfonyl)-4-methylpiperazine.
CATO supplies 1-((3-Chloro-4-fluorophenyl)sulfonyl)-4-methylpiperazine (CAS 613657-40-2), a certified reference material (molecular formula C11H14ClFN2O2S, MW 292.76 g/mol) for analytical method development and quality control.
Structurally, 1-((3-Chloro-4-fluorophenyl)sulfonyl)-4-methylpiperazine (C11H14ClFN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 292.76 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
