Chemical Structure

Tannic Acid CAS 1401-55-4 chemical structure

Description

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.

Tannic Acid (CAS 1401-55-4) is a high-purity analytical reference standard with the molecular formula C76H52O46 and a molecular weight of 1701.20 g/mol.

Structurally, Tannic Acid (C76H52O46) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 51.0, corresponding to approximately 51 ring(s) or double-bond equivalent(s). With a molecular weight of 1701.20 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Tannic Acid 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.
