Chemical Structure
Description
As a certified reference material (CRM), DL-threo-Dihydrosphingosine 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.
DL-threo-Dihydrosphingosine (CAS 73938-69-9), molecular formula C18H39NO2 and molecular weight 301.51 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, DL-threo-Dihydrosphingosine (C18H39NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 301.51 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.
