2-Chloroquinazoline-4-carboxylic acid CAS 944902-11-8

Description

Compared with other compounds in its class, the molecular weight of 208.60 g/mol gives 2-Chloroquinazoline-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloroquinazoline-4-carboxylic acid (CAS 944902-11-8), molecular formula C9H5ClN2O2 and molecular weight 208.60 g/mol, is a CATO reference standard with documented purity and traceability.

2-Chloroquinazoline-4-carboxylic acid (C9H5ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-Chloroquinazoline-4-carboxylic acid 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.
