Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(1E,3S,5Z,8R/S,10S)-3,11-Bis-{[tert-butyl(dimethyl)silyl]oxy}-2,6,10-trimethyl-8-(phenylsulfonyl)undeca-1,5-dienyl]-2-methyl-1,3-thiazole.
4-[(1E,3S,5Z,8R/S,10S)-3,11-Bis-{[tert-butyl(dimethyl)silyl]oxy}-2,6,10-trimethyl-8-(phenylsulfonyl)undeca-1,5-dienyl]-2-methyl-1,3-thiazole (CAS 308357-81-5) is a high-purity analytical reference standard with the molecular formula C36H61NO4S2Si2 and a molecular weight of 692.17 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-[(1E,3S,5Z,8R/S,10S)-3,11-Bis-{[tert-butyl(dimethyl)silyl]oxy}-2,6,10-trimethyl-8-(phenylsulfonyl)undeca-1,5-dienyl]-2-methyl-1,3-thiazole is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 692.17 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-[(1E,3S,5Z,8R/S,10S)-3,11-Bis-{[tert-butyl(dimethyl)silyl]oxy}-2,6,10-trimethyl-8-(phenylsulfonyl)undeca-1,5-dienyl]-2-methyl-1,3-thiazole 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.
