Description
As a certified reference material (CRM), 1-(3-Butyl-6-methyl-3,4-dihydro-2H-furo[3',2':3,4]naphtho[2,1-e][1,3]oxazin-5-yl)ethan-1-one 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.
1-(3-Butyl-6-methyl-3,4-dihydro-2H-furo[3',2':3,4]naphtho[2,1-e][1,3]oxazin-5-yl)ethan-1-one (CAS 526188-52-3), molecular formula C21H23NO3 and molecular weight 337.41 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, 1-(3-Butyl-6-methyl-3,4-dihydro-2H-furo[3',2':3,4]naphtho[2,1-e][1,3]oxazin-5-yl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.41 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.
