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 Quinuclidin-3-yl 2-cyclopentyl-2-hydroxyhex-3-ynoate.
CATO supplies Quinuclidin-3-yl 2-cyclopentyl-2-hydroxyhex-3-ynoate (CAS 101952-37-8), a certified reference material (molecular formula C18H27NO3, MW 305.41 g/mol) for analytical method development and quality control.
Quinuclidin-3-yl 2-cyclopentyl-2-hydroxyhex-3-ynoate (C18H27NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
