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.
(2-((7S,8S)-3-Carboxy-7-(2-carboxyethyl)-18-ethyl-2,8,12,17-tetramethyl-13-vinyl-7H,8H-porphyrin-5-yl)acetyl)-L-aspartic acid (CAS 110230-98-3) is a high-purity analytical reference standard with the molecular formula C38H41N5O9 and a molecular weight of 711.76 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (2-((7S,8S)-3-Carboxy-7-(2-carboxyethyl)-18-ethyl-2,8,12,17-tetramethyl-13-vinyl-7H,8H-porphyrin-5-yl)acetyl)-L-aspartic acid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 711.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
