Chemical Structure
Description
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 supplies 2-Chloro-3-(3,5-difluorophenyl)-1-propene (CAS 951892-72-1), a certified reference material (molecular formula C9H7ClF2, MW 188.60 g/mol) for analytical method development and quality control.
Owing to fluorine/chlorine substitution, an aromatic ring system, 2-Chloro-3-(3,5-difluorophenyl)-1-propene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-Chloro-3-(3,5-difluorophenyl)-1-propene 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.
