3-Methylphthalonitrile CAS 36715-97-6 chemical structure

Description

3-Methylphthalonitrile (CAS 36715-97-6), molecular formula C9H6N2 and molecular weight 142.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Methylphthalonitrile (C9H6N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

CATO manufactures 3-Methylphthalonitrile 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.
