Chemical Structure
Description
As a certified reference material (CRM), Promethazine Impurity 17 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.
CATO supplies Promethazine Impurity 17 (CAS 39796-64-0), a certified reference material (molecular formula C3H9NO2, MW 91.11 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Promethazine Impurity 17 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 91.11 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
