2-Methyl-4-phenylphthalazin-1(2H)-one CAS 49572-99-8

Description

Compared with other compounds in its class, the molecular weight of 236.27 g/mol gives 2-Methyl-4-phenylphthalazin-1(2H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methyl-4-phenylphthalazin-1(2H)-one (CAS 49572-99-8) is a high-purity analytical reference standard with the molecular formula C15H12N2O and a molecular weight of 236.27 g/mol.

The molecular framework of 2-Methyl-4-phenylphthalazin-1(2H)-one (C15H12N2O) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

As a certified reference material (CRM), 2-Methyl-4-phenylphthalazin-1(2H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
