Chemical Structure

Picric Acid CAS 88-89-1 chemical structure

Description

CATO manufactures Picric 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.

Picric Acid (CAS 88-89-1), molecular formula C6H3N3O7 and molecular weight 229.10 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Picric Acid (C6H3N3O7) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 229.10 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.
