Description
CATO manufactures D,L-Tosylisopropylideneglycerol-d5 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.
D,L-Tosylisopropylideneglycerol-d5 (CAS 1330076-68-0) is a high-purity analytical reference standard with the molecular formula C13H13D5O5S and a molecular weight of 291.37 g/mol.
Structurally, D,L-Tosylisopropylideneglycerol-d5 (C13H13D5O5S) contains deuterium isotope labeling, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 291.37 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
