Chemical Structure

1,4,4,6,7-Pentamethyl-2-phenyl-1,4-dihydroquinoline CAS 6971-31-9 chemical structure

Description

CATO manufactures 1,4,4,6,7-Pentamethyl-2-phenyl-1,4-dihydroquinoline 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 1,4,4,6,7-Pentamethyl-2-phenyl-1,4-dihydroquinoline (CAS 6971-31-9), a certified reference material (molecular formula C20H23N, MW 277.40 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1,4,4,6,7-Pentamethyl-2-phenyl-1,4-dihydroquinoline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 277.40 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).

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