Description

Compared with other compounds in its class, the molecular weight of 1761.26 g/mol gives 1397-74-6 6S8G786WHK Acetyltannic acid [USP] Acetyltannic acid EINECS 215-741-7 UNII-6S8G786WHK distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1397-74-6 6S8G786WHK Acetyltannic acid [USP] Acetyltannic acid EINECS 215-741-7 UNII-6S8G786WHK (CAS 1397-74-6) is a high-purity analytical reference standard with the molecular formula C76H52O46C2H4O2 and a molecular weight of 1761.26 g/mol.

1397-74-6 6S8G786WHK Acetyltannic acid [USP] Acetyltannic acid EINECS 215-741-7 UNII-6S8G786WHK (C76H52O46C2H4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
