Description
As a certified reference material (CRM), Benzoxazolium, 3-[2,6-bis(1-methylethyl)phenyl]-5,7-bis(1,1-dimethylethyl)-, tetrafluoroborate(1-) (1:1) 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.
Benzoxazolium, 3-[2,6-bis(1-methylethyl)phenyl]-5,7-bis(1,1-dimethylethyl)-, tetrafluoroborate(1-) (1:1) (CAS 2270864-45-2), molecular formula C27H38NOBF3F and molecular weight 479.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Benzoxazolium, 3-[2,6-bis(1-methylethyl)phenyl]-5,7-bis(1,1-dimethylethyl)-, tetrafluoroborate(1-) (1:1) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 479.41 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
