Chemical Structure
Description
As a certified reference material (CRM), n-Hexadecyltrimethyl-d9-ammonium Bromide 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 n-Hexadecyltrimethyl-d9-ammonium Bromide (CAS 95217-14-4), a certified reference material (molecular formula C19H33D9NBr, MW 373.51 g/mol) for analytical method development and quality control.
Structurally, n-Hexadecyltrimethyl-d9-ammonium Bromide (C19H33D9NBr) contains deuterium isotope labeling, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 373.51 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
