Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 84.14 g/mol gives 1,3-Propanediol-d8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Propanediol-d8 (CAS 285978-25-8), molecular formula C3D8O2 and molecular weight 84.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3-Propanediol-d8 (C3D8O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 84.14 g/mol, it falls into the low-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,3-Propanediol-d8 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
