24991-47-7 Poly(4-chlorostyrene) CAS 24991-47-7 chemical structure

Description

CATO manufactures 24991-47-7 Poly(4-chlorostyrene) 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.

CATO supplies 24991-47-7 Poly(4-chlorostyrene) (CAS 24991-47-7), a certified reference material (molecular formula C8H13Cl, MW 144.64 g/mol) for analytical method development and quality control.

The molecular framework of 24991-47-7 Poly(4-chlorostyrene) (C8H13Cl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
