4-Methylstyrene CAS 622-97-9

Description

The occurrence of 4-Methylstyrene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Methylstyrene (CAS 622-97-9), a certified reference material (molecular formula C9H10, MW 118.18 g/mol) for analytical method development and quality control.

Owing to an aromatic ring system, 4-Methylstyrene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 118.18 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).

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 4-Methylstyrene 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.
