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 2-Chloro-3-(phenylselanyl)tetrahydro-2H-pyran.
CATO supplies 2-Chloro-3-(phenylselanyl)tetrahydro-2H-pyran (CAS 89113-96-2), a certified reference material (molecular formula C11H13ClOSe, MW 275.63 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-3-(phenylselanyl)tetrahydro-2H-pyran (C11H13ClOSe) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
