Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,2,2,2-pentadeuterioethyl (5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoate.
CATO supplies 1,1,2,2,2-pentadeuterioethyl (5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoate (CAS 1331642-74-0), a certified reference material (molecular formula C22H31D5O2, MW 337.55 g/mol) for analytical method development and quality control.
Structurally, 1,1,2,2,2-pentadeuterioethyl (5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoate (C22H31D5O2) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 337.55 g/mol, it falls into the moderately-high-molecular-weight range. 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.
