Description

Compared with other compounds in its class, the molecular weight of 208.64 g/mol gives 2-Chloro-5-methoxy-4-methylquinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-5-methoxy-4-methylquinazoline (CAS 1429782-11-5) is a high-purity analytical reference standard with the molecular formula C10H9ClN2O and a molecular weight of 208.64 g/mol.

The molecular framework of 2-Chloro-5-methoxy-4-methylquinazoline (C10H9ClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 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.

As a certified reference material (CRM), 2-Chloro-5-methoxy-4-methylquinazoline 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.
