4-Hydroxy-3-methylbenzonitrile CAS 15777-70-5 chemical structure

Description

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

4-Hydroxy-3-methylbenzonitrile (CAS 15777-70-5) is a high-purity analytical reference standard with the molecular formula C8H7NO and a molecular weight of 133.15 g/mol.

The molecular framework of 4-Hydroxy-3-methylbenzonitrile (C8H7NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 4-Hydroxy-3-methylbenzonitrile 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.
