Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1H-indole-1-carboxylic acid, 4-[[(methylsulfonyl)oxy]methyl]-, 1,1-dimethylethyl ester (CAS 1056894-30-4) is a high-purity analytical reference standard with the molecular formula C15H19NO5S and a molecular weight of 325.38 g/mol.
The molecular framework of 1H-indole-1-carboxylic acid, 4-[[(methylsulfonyl)oxy]methyl]-, 1,1-dimethylethyl ester (C15H19NO5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 1H-indole-1-carboxylic acid, 4-[[(methylsulfonyl)oxy]methyl]-, 1,1-dimethylethyl ester 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.
