Description
As a certified reference material (CRM), 960069-81-2 Alpha-[5-(1,2-dithiolan-3-yl)pentamido]-omega-biotinyl undeca(ethylene glycol) 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.
960069-81-2 Alpha-[5-(1,2-dithiolan-3-yl)pentamido]-omega-biotinyl undeca(ethylene glycol) (CAS 960069-81-2), molecular formula C42H78N4O14S3 and molecular weight 959.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 960069-81-2 Alpha-[5-(1,2-dithiolan-3-yl)pentamido]-omega-biotinyl undeca(ethylene glycol) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 959.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
