Chemical Structure
Description
As a certified reference material (CRM), D-arabino C20-Phytosphingosine 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.
D-arabino C20-Phytosphingosine (CAS 1335002-11-3) is a high-purity analytical reference standard with the molecular formula C20H43NO3 and a molecular weight of 345.56 g/mol.
The molecular framework of D-arabino C20-Phytosphingosine (C20H43NO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
