Chemical Structure

2-Acetyl-5-nitrobenzoic acid CAS 58335-61-8 chemical structure

Description

The occurrence of 2-Acetyl-5-nitrobenzoic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Acetyl-5-nitrobenzoic acid (CAS 58335-61-8), molecular formula C9H8NO5 and molecular weight 210.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Acetyl-5-nitrobenzoic acid (C9H8NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 210.16 g/mol, it falls into the medium-molecular-weight range. 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-Acetyl-5-nitrobenzoic 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.
