Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 15777-44-3 KST-1B0726 {5b-[(2,3-dimethylbutanoyl)oxy]-9a-(dodecanoyloxy)-5,5a-dihydroxy-1,1,6a,8-tetramethyl-10-oxo-1a,2,5,5a,5b,6a,7,8,9,9a-decahydro-1h-2,7a-methanocyclopropa[5',6']cyclodeca[1',2':3,4]cyclopenta[1,2-b]oxiren-4-yl}methyl hexadecanoate.

15777-44-3 KST-1B0726 {5b-[(2,3-dimethylbutanoyl)oxy]-9a-(dodecanoyloxy)-5,5a-dihydroxy-1,1,6a,8-tetramethyl-10-oxo-1a,2,5,5a,5b,6a,7,8,9,9a-decahydro-1h-2,7a-methanocyclopropa[5',6']cyclodeca[1',2':3,4]cyclopenta[1,2-b]oxiren-4-yl}methyl hexadecanoate (CAS 15777-44-3), molecular formula C8H12ClN3OS and molecular weight 233.72 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H12ClN3OS, 15777-44-3 KST-1B0726 {5b-[(2,3-dimethylbutanoyl)oxy]-9a-(dodecanoyloxy)-5,5a-dihydroxy-1,1,6a,8-tetramethyl-10-oxo-1a,2,5,5a,5b,6a,7,8,9,9a-decahydro-1h-2,7a-methanocyclopropa[5',6']cyclodeca[1',2':3,4]cyclopenta[1,2-b]oxiren-4-yl}methyl hexadecanoate contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 233.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
