Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benazolin-ethyl Impurity 17.
Benazolin-ethyl Impurity 17 (CAS 898748-63-5) is a high-purity analytical reference standard with the molecular formula C7H3ClN2O3S and a molecular weight of 230.63 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Benazolin-ethyl Impurity 17 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.63 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.
As a certified reference material (CRM), Benazolin-ethyl 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.
