Chemical Structure

2,4-Dinitro-5-fluorotoluene CAS 349-01-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Dinitro-5-fluorotoluene.

2,4-Dinitro-5-fluorotoluene (CAS 349-01-9) is a high-purity analytical reference standard with the molecular formula C7H5FN2O4 and a molecular weight of 200.12 g/mol.

The molecular framework of 2,4-Dinitro-5-fluorotoluene (C7H5FN2O4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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).

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), 2,4-Dinitro-5-fluorotoluene 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.
