Chemical Structure

Linoleic acid-d<SUB>32</SUB> CAS 33512-37-7 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 Linoleic acid-d<SUB>32</SUB>.

Linoleic acid-d<SUB>32</SUB> (CAS 33512-37-7) is a high-purity analytical reference standard with the molecular formula C18D32O2 and a molecular weight of 312.64 g/mol.

Structurally, Linoleic acid-d<SUB>32</SUB> (C18D32O2) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 312.64 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

CATO manufactures Linoleic acid-d<SUB>32</SUB> under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
