Chemical Structure

Etomidate Impurity 19（Mixture of Tautomers） CAS CATO-C4X-188419 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Etomidate Impurity 19（Mixture of Tautomers） is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.19 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.

As a process- or degradation-related impurity, Etomidate Impurity 19（Mixture of Tautomers） (CAS CATO-C4X-188419, C9H11NO) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Etomidate Impurity 19（Mixture of Tautomers） under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
