Description

The occurrence of (4ar,12as,12br,12cs)-10-hydroxy-15-methyl-4a,5,12,12a,12b,12c-hexahydro-11h-6a,4-(ethanoiminomethano)-1-oxa-10b-azacyclohepta[1,2,3-cd]fluoranthene-6,11(2h)-dione 22691-02-7 KST-1A2868 is closely related to a salt form, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(4ar,12as,12br,12cs)-10-hydroxy-15-methyl-4a,5,12,12a,12b,12c-hexahydro-11h-6a,4-(ethanoiminomethano)-1-oxa-10b-azacyclohepta[1,2,3-cd]fluoranthene-6,11(2h)-dione 22691-02-7 KST-1A2868 (CAS 22691-02-7) is a high-purity analytical reference standard with the molecular formula CaCl2H2O and a molecular weight of 128.99 g/mol.

Owing to a salt form, chlorine substitution, (4ar,12as,12br,12cs)-10-hydroxy-15-methyl-4a,5,12,12a,12b,12c-hexahydro-11h-6a,4-(ethanoiminomethano)-1-oxa-10b-azacyclohepta[1,2,3-cd]fluoranthene-6,11(2h)-dione 22691-02-7 KST-1A2868 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
