Chemical Structure
Description
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Articaine Hydrochloride EP Impurity I is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Articaine Hydrochloride EP Impurity I (CAS 85006-31-1) is a certified pharmaceutical impurity reference standard with the molecular formula C7H9NO2S and a molecular weight of 171.22 g/mol.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Articaine Hydrochloride EP Impurity I 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.
