7-Fluoroquinazoline CAS 16499-45-9 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.

7-Fluoroquinazoline (CAS 16499-45-9), molecular formula C8H5FN2 and molecular weight 148.14 g/mol, is a CATO reference standard with documented purity and traceability.

7-Fluoroquinazoline (C8H5FN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
