Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,5R,8R,11R)-11-((1H-Indol-3-yl)methyl)-14-amino-2,5-dibenzyl-8-(4-hydroxybenzyl)-4,7,10,13-tetraoxo-3,6,9,12-tetraazatetradecan-1-oic acid.

CATO supplies (2R,5R,8R,11R)-11-((1H-Indol-3-yl)methyl)-14-amino-2,5-dibenzyl-8-(4-hydroxybenzyl)-4,7,10,13-tetraoxo-3,6,9,12-tetraazatetradecan-1-oic acid (CAS 644997-10-4), a certified reference material (molecular formula C40H42N6O7, MW 718.80 g/mol) for analytical method development and quality control.

Structurally, (2R,5R,8R,11R)-11-((1H-Indol-3-yl)methyl)-14-amino-2,5-dibenzyl-8-(4-hydroxybenzyl)-4,7,10,13-tetraoxo-3,6,9,12-tetraazatetradecan-1-oic acid (C40H42N6O7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 23.0, corresponding to approximately 23 ring(s) or double-bond equivalent(s). With a molecular weight of 718.80 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
