Description

As a certified reference material (CRM), [2-oxo-2-[(2S,4S)-2,5,12-trihydroxy-7-methoxy-4-[[(2S,4R,6S,7S,9R,10S)-10-methoxy-6-methyl-5,8,11-trioxa-1-azatricyclo[7.4.0.0²⁷]tridecan-4-yl]oxy]-6,11-dioxo-3,4-dihydro-1H-tetracen-2-yl]ethyl] N-[2-[[4-[[(2S)-2-[[(2S)-2-[4-[4-(2,5-dioxopyrrol-1-yl)phenyl]butanoylamino]-3-methyl-butanoyl]amino]-5-ureido-pentanoyl]amino]phenyl]methoxycarbonyl-methyl-amino]ethyl]-N-methyl-carbamate 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.

[2-oxo-2-[(2S,4S)-2,5,12-trihydroxy-7-methoxy-4-[[(2S,4R,6S,7S,9R,10S)-10-methoxy-6-methyl-5,8,11-trioxa-1-azatricyclo[7.4.0.0²⁷]tridecan-4-yl]oxy]-6,11-dioxo-3,4-dihydro-1H-tetracen-2-yl]ethyl] N-[2-[[4-[[(2S)-2-[[(2S)-2-[4-[4-(2,5-dioxopyrrol-1-yl)phenyl]butanoylamino]-3-methyl-butanoyl]amino]-5-ureido-pentanoyl]amino]phenyl]methoxycarbonyl-methyl-amino]ethyl]-N-methyl-carbamate (CAS 2259318-54-0) is a high-purity analytical reference standard with the molecular formula C70H83N9O22 and a molecular weight of 1402.46 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, [2-oxo-2-[(2S,4S)-2,5,12-trihydroxy-7-methoxy-4-[[(2S,4R,6S,7S,9R,10S)-10-methoxy-6-methyl-5,8,11-trioxa-1-azatricyclo[7.4.0.0²⁷]tridecan-4-yl]oxy]-6,11-dioxo-3,4-dihydro-1H-tetracen-2-yl]ethyl] N-[2-[[4-[[(2S)-2-[[(2S)-2-[4-[4-(2,5-dioxopyrrol-1-yl)phenyl]butanoylamino]-3-methyl-butanoyl]amino]-5-ureido-pentanoyl]amino]phenyl]methoxycarbonyl-methyl-amino]ethyl]-N-methyl-carbamate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1402.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
