Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-{[1-(Cyclopropylcarbonyl)-2,3-dihydro-1H-indol-5-yl]sulfonyl}propanoic acid.
3-{[1-(Cyclopropylcarbonyl)-2,3-dihydro-1H-indol-5-yl]sulfonyl}propanoic acid (CAS 1170565-67-9) is a high-purity analytical reference standard with the molecular formula C15H17NO5S and a molecular weight of 323.36 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-{[1-(Cyclopropylcarbonyl)-2,3-dihydro-1H-indol-5-yl]sulfonyl}propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
