3,4-Dichloro-5-nitrobenzotrifluoride CAS 657-02-3 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 3,4-Dichloro-5-nitrobenzotrifluoride.

3,4-Dichloro-5-nitrobenzotrifluoride (CAS 657-02-3), molecular formula C7H2Cl2F3NO2 and molecular weight 260.00 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,4-Dichloro-5-nitrobenzotrifluoride (C7H2Cl2F3NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 260.00 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 3,4-Dichloro-5-nitrobenzotrifluoride 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.
