Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 68696-18-4 Tetramethylammonium chloride hydrate tetraethylammonium chloride hydrate (CAS 68696-18-4), a certified reference material (molecular formula C8H20NClH2O, MW 183.72 g/mol) for analytical method development and quality control.
Structurally, 68696-18-4 Tetramethylammonium chloride hydrate tetraethylammonium chloride hydrate (C8H20NClH2O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -2.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 183.72 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 68696-18-4 Tetramethylammonium chloride hydrate tetraethylammonium chloride hydrate 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.
