Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1ar,1bs,4ar,7as,7bs,8r,9r,9as)-7b-hydroxy-3-(hydroxymethyl)-4a-methoxy-1,1,6,8-tetramethyl-5-oxo-1,1a,1b,4,4a,5,7a,7b,8,9-decahydro-9ah-cyclopropa[3,4]benzo[1,2-e]azulene-9,9a-diyl didecanoate 56601-42-4 KST-1A6084.
CATO supplies (1ar,1bs,4ar,7as,7bs,8r,9r,9as)-7b-hydroxy-3-(hydroxymethyl)-4a-methoxy-1,1,6,8-tetramethyl-5-oxo-1,1a,1b,4,4a,5,7a,7b,8,9-decahydro-9ah-cyclopropa[3,4]benzo[1,2-e]azulene-9,9a-diyl didecanoate 56601-42-4 KST-1A6084 (CAS 56601-42-4), a certified reference material (molecular formula C4H5NS, MW 99.15 g/mol) for analytical method development and quality control.
(1ar,1bs,4ar,7as,7bs,8r,9r,9as)-7b-hydroxy-3-(hydroxymethyl)-4a-methoxy-1,1,6,8-tetramethyl-5-oxo-1,1a,1b,4,4a,5,7a,7b,8,9-decahydro-9ah-cyclopropa[3,4]benzo[1,2-e]azulene-9,9a-diyl didecanoate 56601-42-4 KST-1A6084 (C4H5NS) contains a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
